teyrebaz33 1caee06b22 fix: tool call repair — auto-lowercase, fuzzy match, helpful error on unknown tool (#520) ...

- Add _repair_tool_call(): tries lowercase, normalize, then fuzzy match (difflib 0.7)
- Replace 3-retry-then-abort with graceful error: model receives helpful message and self-corrects
- Conversation stays alive instead of dying on hallucinated tool names

Closes #520
