fix: prevent Kimi K2 model from completing tasks without performing actions

[roomote]

This PR fixes issue #5999 where the Kimi K2 model immediately marks tasks as completed without actually performing any fixes.

Changes Made

1. Added validation in attemptCompletionTool to check if actual work was done before allowing completion

   • Checks if any tools were used or files were edited
   • Specifically targets Kimi K2 models through case-insensitive model ID detection

2. Added model-specific instructions in the system prompt for Kimi K2 models

   • Instructs the model to complete implementation before using attempt_completion
   • Emphasizes the need to perform actual work before marking tasks complete

3. Added telemetry tracking for premature completion attempts

   • Tracks when Kimi K2 models attempt to complete without doing work
   • Helps monitor the effectiveness of this fix

4. Comprehensive test coverage for the new validation logic

   • Tests various scenarios including tool usage, file edits, and model detection
   • Ensures the fix works correctly for Kimi K2 while not affecting other models

Testing

• All existing tests pass
• Added new test suite specifically for Kimi K2 validation
• Manually tested the validation logic

Fixes #5999

This is not how we should fix this, it seems that this is a problem with the AI model itself, not Roo Code
