teknium1 cc61f54cd3 feat: add ACP (Agent Client Protocol) server for editor integration
Complete ACP implementation enabling hermes-agent to work as a coding
agent inside VS Code, Zed, JetBrains IDEs, and any ACP-compatible editor.

Based on PR #837 by teknium1, with full implementation of the prompt flow
and fixes for broken event bridging.

## ACP Adapter (acp_adapter/, ~1200 lines)

server.py — HermesACPAgent with all 15 Agent protocol methods:
  - Full session lifecycle (new, load, resume, list, fork, cancel)
  - prompt() runs AIAgent in thread executor, streams tool events,
    thinking, and agent messages back to the editor in real-time
  - Permission bridging for dangerous command approval dialogs
  - Model switching support

session.py — Thread-safe SessionManager with per-session AIAgent,
  conversation history, and model tracking

events.py — Callback factories bridging AIAgent's sync callbacks to
  ACP's async notifications via run_coroutine_threadsafe()

tools.py — Tool kind mapping (25+ tools) with human-readable titles,
  diff content for file edits, and result truncation

permissions.py — Maps ACP permission dialogs to hermes approval flow
auth.py — Provider credential detection
entry.py — CLI entry point with stderr logging

## Key Design Decisions

- No modifications to run_agent.py — ACP works entirely through
  AIAgent's existing callback system (tool_progress_callback,
  thinking_callback, step_callback)
- File edits shown as diffs in the editor (FileEditToolCallContent)
- Terminal commands shown with $ prefix
- Large tool outputs truncated for the UI (5000 char limit)
- Approval for dangerous commands routed to editor permission dialog

## Also includes
- jupyter-live-kernel skill for data science workflows
- acp_registry/ with agent.json for editor auto-discovery
- docs/acp-setup.md with VS Code, Zed, JetBrains setup guides
- hermes acp CLI subcommand

## Tests
- 81 new ACP tests covering server, session, events, tools, auth,
  permissions
- Full suite: 3330 passed, 16 skipped

Closes #837

Hermes Agent

Hermes Agent ⚕

Documentation Discord License: MIT Built by Nous Research

The self-improving AI agent built by Nous Research. It's the only agent with a built-in learning loop — it creates skills from experience, improves them during use, nudges itself to persist knowledge, searches its own past conversations, and builds a deepening model of who you are across sessions. Run it on a $5 VPS, a GPU cluster, or serverless infrastructure that costs nearly nothing when idle. It's not tied to your laptop — talk to it from Telegram while it works on a cloud VM.

Use any model you want — Nous Portal, OpenRouter (200+ models), z.ai/GLM, Kimi/Moonshot, MiniMax, OpenAI, or your own endpoint. Switch with hermes model — no code changes, no lock-in.

A real terminal interfaceFull TUI with multiline editing, slash-command autocomplete, conversation history, interrupt-and-redirect, and streaming tool output.
Lives where you doTelegram, Discord, Slack, WhatsApp, Signal, and CLI — all from a single gateway process. Voice memo transcription, cross-platform conversation continuity.
A closed learning loopAgent-curated memory with periodic nudges. Autonomous skill creation after complex tasks. Skills self-improve during use. FTS5 session search with LLM summarization for cross-session recall. Honcho dialectic user modeling. Compatible with the agentskills.io open standard.
Scheduled automationsBuilt-in cron scheduler with delivery to any platform. Daily reports, nightly backups, weekly audits — all in natural language, running unattended.
Delegates and parallelizesSpawn isolated subagents for parallel workstreams. Write Python scripts that call tools via RPC, collapsing multi-step pipelines into zero-context-cost turns.
Runs anywhere, not just your laptopSix terminal backends — local, Docker, SSH, Daytona, Singularity, and Modal. Daytona and Modal offer serverless persistence — your agent's environment hibernates when idle and wakes on demand, costing nearly nothing between sessions. Run it on a $5 VPS or a GPU cluster.
Research-readyBatch trajectory generation, Atropos RL environments, trajectory compression for training the next generation of tool-calling models.
