Full Release Notes

## Fixes

- **Fix #38**: Panic when truncating Chinese/multi-byte text — `cap_str` was slicing by byte index, causing `byte index is not a char boundary` panic with Chinese characters, emoji, or other multi-byte UTF-8 text
- **Fix #35**: Improved error message for LLM failures — was showing "Invalid request format. This may be a bug" which confused users; now shows "Check your API key and model configuration in Settings"
- **13 additional UTF-8 boundary fixes** across compactor, session_repair, loop_guard, image_gen, tool_runner, tts, and workspace_context — all string truncation sites now use safe char-boundary-aware slicing
- Added `safe_truncate_str` utility with 7 unit tests for safe multi-byte string truncation
