- Added a trap command in `check-package-data.sh` to ensure cleanup of temporary files on exit.
- Improved error handling in `context_checkpoint.sh` for flushing pending bugs to `BUGS.md`, providing warnings if write operations fail.
- Implemented file locking in `post_tool_counter.sh` to ensure atomic increment of the tool counter, preventing race conditions.
These changes improve the reliability and robustness of package data checks and related scripts.
