Bill 1e7bdb509b chore: remove debug logging from ContextInjector
Removed noisy debug print statements that were added during
troubleshooting. The context injection is now working correctly
and no longer needs diagnostic output.

Cleaned up:
- Entry point logging
- Before/after injection logging
- Tool name and args logging
