Add tools/tool_result_storage.py implementing Layer 2 (per-result) and
Layer 3 (per-turn budget) persistence for large tool outputs. Results
exceeding thresholds are written to disk with a <persisted-output>
preview block replacing the inline content. Extend ToolEntry and
ToolRegistry with max_result_size_chars for per-tool threshold control.
