feat(tui): implement optimized transcript pane with virtualization

Replace the standard ScrollBox with a new OptimizedTranscriptPane component
that uses the FixedWindowScroller for virtualized message rendering:

1. Implement OptimizedTranscriptPane as a drop-in replacement
   - Preserves all existing functionality
   - Maintains same rendering logic for messages
   - Uses efficient virtualization under the hood

2. Integrate OptimizedTranscriptPane with appLayout
   - Enable performance mode by default
   - Preserve layout and scrollbar positioning
   - Keep the original implementation as fallback

This completes the TUI performance optimizations for long sessions,
addressing scrolling lag and input jitter by dramatically reducing
DOM nodes and layout calculations.

+"""Azure Foundry endpoint auto-detection.
+
+Inspect an Azure AI Foundry / Azure OpenAI endpoint to determine:
+  - API transport (OpenAI-style ``chat_completions`` vs
+    Anthropic-style ``anthropic_messages``)
+  - Available models (best effort — Azure does not expose a deployment
+    listing via the inference API key, but Azure OpenAI v1 endpoints
+    return the resource's model catalog via ``GET /models``)
+  - Context length for each discovered/entered model, via the existing
+    :func:`agent.model_metadata.get_model_context_length` resolver.
+
+Rationale:
+
+Azure has no pure-API-key deployment-listing endpoint — per Microsoft,
+deployment enumeration requires ARM management-plane auth.  Azure
+OpenAI v1 endpoints ``{resource}.openai.azure.com/openai/v1`` do return
+a ``/models`` list, but it reflects the resource's *available* models
+rather than the user's *deployed* deployment names.  In practice it is
+still a useful hint — the user picks a familiar model name and we look
+up its context length from the catalog.
+
+The detector never crashes on errors (every HTTP call is wrapped in a
+broad try/except).  Callers get a :class:`DetectionResult` with whatever
+information could be gathered, and fall back to manual entry for the
+rest.

+# TUI Performance Analysis
+
+## Issues Identified
+
+1. **Scrolling lag with large message history**
+   - No virtualization or windowing in message rendering
+   - Each message re-renders on scroll
+   - Complete DOM reconstruction on each render
+
+2. **Input jitter with scrollbar**
+   - Composer width changes when scrollbar appears/disappears
+   - Layout shifts when scrolling near bottom
+
+3. **Layout thrashing**
+   - Multiple successive layout recalculations
+   - Excessive style computations in the render loop
+
+## Investigation Areas
+
+### 1. Message Rendering Performance
+
+Current implementation in `messageLine.tsx` renders all messages in the transcript without virtualization. For long sessions, this means:
+
+- Every message is always in the DOM
+- Complete re-rendering happens on each state change
+- No windowing or culling of off-screen content
+- Layout recalculations for entire transcript on each scroll
+
+### 2. Re-rendering Optimization
+
+- No memoization of message components
+- No element recycling 
+- Each message potentially triggers layout shifts
+
+### 3. Scrollbar Behavior
+
+- Composer width calculation doesn't account for scrollbar presence
+- No stable layout constraints
+
+## Proposed Solutions
+
+### 1. Implement Virtualized List for Messages
+
+Add `react-window` or similar virtualization library to render only visible messages:
+
+```tsx
+import { FixedSizeList as List } from 'react-window';
+
+// In the component render
+<List
+  height={viewportHeight}
+  itemCount={messages.length}
+  itemSize={estimatedRowHeight}
+  width="100%"
+  overscanCount={5}
+>
+  {({ index, style }) => (
+    <div style={style}>
+      <MessageLine message={messages[index]} />
+    </div>
+  )}
+</List>
+```
+
+### 2. Memoize Message Components
+
+Use `React.memo` to prevent unnecessary re-renders:
+
+```tsx
+const MessageLine = React.memo(({ message, ...props }) => {
+  // Component logic
+}, (prevProps, nextProps) => {
+  // Custom comparison logic
+  return prevProps.message.id === nextProps.message.id && 
+         prevProps.message.content === nextProps.message.content;
+});
+```
+
+### 3. Fix Scrollbar Layout Issues
+
+- Add scrollbar-gutter CSS to reserve space for scrollbar
+- Stabilize layout with fixed container dimensions
+
+```css
+.message-container {
+  scrollbar-gutter: stable;
+  overflow-y: auto;
+}
+```
+
+### 4. Add Performance Measurements
+
+Add performance monitoring to identify bottlenecks:
+
+```tsx
+useEffect(() => {
+  const start = performance.now();
+  // Measure key operations
+  return () => {
+    console.log(`Operation took ${performance.now() - start}ms`);
+  };
+}, [dependencyArray]);
+```
+
+## Implementation Plan
+
+1. Add virtualization for message rendering
+2. Implement memo optimization for components
+3. Fix scrollbar layout issues
+4. Add performance monitoring
+5. Optimize re-render triggers
+6. Improve scroll restoration

 - If you load a queued item into the input and resubmit plain text, that queue item is replaced, removed from the queue preview, and promoted to send next. If the agent is still busy, the edited item is moved to the front of the queue and sent after the current run completes.
 - Completion requests are debounced by 60 ms. Input starting with `/` uses `complete.slash`. A trailing token that starts with `./`, `../`, `~/`, `/`, or `@` uses `complete.path`.
 - Text pastes are inserted inline directly into the draft. Nothing is newline-flattened.

+title: "Azure AI Foundry"
+description: "Use Hermes Agent with Azure AI Foundry — OpenAI-style and Anthropic-style endpoints, auto-detection of transport and deployed models"
+---
+
+# Azure AI Foundry
+
+Hermes Agent supports Azure AI Foundry (and Azure OpenAI) as a first-class provider. A single Azure resource can host models with two different wire formats:
+
+- **OpenAI-style** — `POST /v1/chat/completions` on endpoints like `https://<resource>.openai.azure.com/openai/v1`. Used for GPT-4.x, GPT-5.x, Llama, Mistral, and most open-weight models.
+- **Anthropic-style** — `POST /v1/messages` on endpoints like `https://<resource>.services.ai.azure.com/anthropic`. Used when Azure Foundry serves Claude models via the Anthropic Messages API format.
+
+The setup wizard probes your endpoint and auto-detects which transport it uses, which deployments are available, and each model's context length.
+
+## Prerequisites
+
+- An Azure AI Foundry or Azure OpenAI resource with at least one deployment
+- An API key for that resource (available in the Azure Portal under "Keys and Endpoint")
+- The deployment's endpoint URL
+
+## Quick Start
+
+```bash
+hermes model
+# → Select "Azure Foundry"
+# → Enter your endpoint URL
+# → Enter your API key
+# Hermes probes the endpoint and auto-detects transport + models
+# → Pick a model from the list (or type a deployment name manually)
+```
+
+The wizard will:
+
+1. **Sniff the URL path** — URLs ending in `/anthropic` are recognised as Azure Foundry Claude routes.
+2. **Probe `GET <base>/models`** — if the endpoint returns an OpenAI-shaped model list, Hermes switches to `chat_completions` and prefills a picker with the returned deployment IDs.
+3. **Probe Anthropic Messages shape** — fallback for endpoints that do not expose `/models` but do accept the Anthropic Messages format.
+4. **Fall back to manual entry** — private/gated endpoints that reject every probe still work; you pick the API mode and type a deployment name by hand.
+
+Context length for the chosen model is resolved via Hermes' standard metadata chain (`models.dev`, provider metadata, and hardcoded family fallbacks) and stored in `config.yaml` so the model can size its own context window correctly.
+
+## Configuration (written to `config.yaml`)
+
+After running the wizard you'll see something like this:
+
+```yaml
+model:
+  provider: azure-foundry
+  base_url: https://my-resource.openai.azure.com/openai/v1
+  api_mode: chat_completions         # or "anthropic_messages"
+  default: gpt-5.4-mini              # your deployment / model name
+  context_length: 400000             # auto-detected
+```
+
+And in `~/.hermes/.env`:
+
+```
+AZURE_FOUNDRY_API_KEY=<your-azure-key>
+```
+
+## OpenAI-style endpoints (GPT, Llama, etc.)
+
+Azure OpenAI's v1 GA endpoint accepts the standard `openai` Python client with minimal changes:
+
+```yaml
+model:
+  provider: azure-foundry
+  base_url: https://my-resource.openai.azure.com/openai/v1
+  api_mode: chat_completions
+  default: gpt-5.4
+```
+
+Important behaviour:
+
+- **gpt-5.x stays on `/chat/completions`.** Unlike `api.openai.com`, Azure OpenAI does not support the Responses API — Hermes detects Azure endpoints and keeps gpt-5.x on `chat_completions` where Azure actually serves it.
+- **`max_completion_tokens` is used automatically.** Azure OpenAI (like direct OpenAI) requires `max_completion_tokens` for gpt-4o, o-series, and gpt-5.x models. Hermes sends the right parameter based on the endpoint.
+- **Pre-v1 endpoints that require `api-version`.** If you have a legacy base URL like `https://<resource>.openai.azure.com/openai?api-version=2025-04-01-preview`, Hermes extracts the query string and forwards it via `default_query` on every request (the OpenAI SDK otherwise drops it when joining paths).
+
+## Anthropic-style endpoints (Claude via Azure Foundry)
+
+For Claude deployments, use the Anthropic-style route:
+
+```yaml
+model:
+  provider: azure-foundry
+  base_url: https://my-resource.services.ai.azure.com/anthropic
+  api_mode: anthropic_messages
+  default: claude-sonnet-4-6
+```
+
+Important behaviour:
+
+- **`/v1` is stripped from the base URL.** The Anthropic SDK appends `/v1/messages` to every request URL — Hermes removes any trailing `/v1` before handing the URL to the SDK to avoid double-`/v1` paths.
+- **`api-version` is sent via `default_query`, not appended to the URL.** Azure Anthropic requires an `api-version` query string. Baking it into the base URL produces malformed paths like `/anthropic?api-version=.../v1/messages` and returns 404. Hermes passes `api-version=2025-04-15` via the Anthropic SDK's `default_query` instead.
+- **OAuth token refresh is disabled.** Azure deployments use static API keys. The `~/.claude/.credentials.json` OAuth token refresh loop that applies to Anthropic Console is explicitly skipped for Azure endpoints to prevent the Claude Code OAuth token from overwriting your Azure key mid-session.
+
+## Alternative: `provider: anthropic` + Azure base URL
+
+If you already have `provider: anthropic` configured and just want to point it at Azure AI Foundry for Claude, you can skip the `azure-foundry` provider entirely:
+
+```yaml
+model:
+  provider: anthropic
+  base_url: https://my-resource.services.ai.azure.com/anthropic
+  api_key_env: AZURE_ANTHROPIC_KEY
+  default: claude-sonnet-4-6
+```
+
+With `AZURE_ANTHROPIC_KEY` set in `~/.hermes/.env`. Hermes detects `azure.com` in the base URL and short-circuits around the Claude Code OAuth token chain so the Azure key is used directly with `x-api-key` auth.
+
+## Model discovery
+
+Azure does **not** expose a pure-API-key endpoint to list your *deployed* model deployments. Deployment enumeration requires Azure Resource Manager authentication (`az cognitiveservices account deployment list`) with an Azure AD principal, not the inference API key.
+
+What Hermes can do:
+
+- Azure OpenAI v1 endpoints (`<resource>.openai.azure.com/openai/v1`) expose `GET /models` with the resource's **available** model catalog. Hermes uses this list to prefill the model picker.
+- Azure Foundry `/anthropic` routes: detected via URL path, model name entered manually.
+- Private / firewalled endpoints: manual entry with a friendly "couldn't probe" message.
+
+You can always type a deployment name directly — Hermes does not validate against the returned list.
+
+## Environment variables
+
+| Variable | Purpose |
+|----------|---------|
+| `AZURE_FOUNDRY_API_KEY` | Primary API key for Azure AI Foundry / Azure OpenAI |
+| `AZURE_FOUNDRY_BASE_URL` | Endpoint URL (set via `hermes model`; env var is used as a fallback) |
+| `AZURE_ANTHROPIC_KEY` | Used by `provider: anthropic` + Azure base URL (alternative to `ANTHROPIC_API_KEY`) |
+
+## Troubleshooting
+
+**401 Unauthorized on gpt-5.x deployments.**
+Azure serves gpt-5.x on `/chat/completions`, not `/responses`. Hermes handles this automatically when the URL contains `openai.azure.com`, but if you see a 401 with an `Invalid API key` body, check that `api_mode` in your `config.yaml` is `chat_completions`.
+
+**404 on `/v1/messages?api-version=.../v1/messages`.**
+This is the malformed-URL bug from pre-fix Azure Anthropic setups. Upgrade Hermes — the `api-version` parameter is now passed via `default_query` rather than baked into the base URL, so the SDK can't corrupt it during URL joining.
+
+**Wizard says "Auto-detection incomplete."**
+The endpoint rejected both the `/models` probe and the Anthropic Messages probe. This is normal for private endpoints behind a firewall or with an IP allow-list. Fall back to manual API mode selection and type your deployment name — everything still works, Hermes just can't prefill the picker.
+
+**Wrong transport picked.**
+Run `hermes model` again and the wizard will re-probe. If the probe still picks the wrong mode, you can edit `config.yaml` directly:
+
+```yaml
+model:
+  provider: azure-foundry
+  api_mode: anthropic_messages   # or chat_completions
+```

 :::warning `"main"` is for auxiliary tasks only
 The `"main"` provider option means "use whatever provider my main agent uses" — it's only valid inside `auxiliary:`, `compression:`, and `fallback_model:` configs. It is **not** a valid value for your top-level `model.provider` setting. If you use a custom OpenAI-compatible endpoint, set `provider: custom` in your `model:` section. See [AI Providers](/docs/integrations/providers) for all main model provider options.
