- Fixed bash tool hanging with background jobs by implementing timeout-based cancellation and draining stdout/stderr pipes instead of waiting indefinitely for EOF.
- Fixed crash when auto-reading large @mentions by adding file size validation (5MB for text, 25MB for images) before reading file contents.
- Prevented out-of-memory issues by skipping files exceeding size limits and displaying file size information in UI for skipped files.
- Added GB file size formatting support to handle very large files in human-readable format.
- Added file size display in UI for skipped files to inform users why files were not included.
- Added test case verifying bash executor returns correctly when command spawns background jobs.
