Merge main into feat/stdin-stdout-pipeline-issue-65

Resolved dependency conflicts in go.mod and go.sum:
- Kept newer golang.org/x/sys v0.38.0 (was v0.13.0 in main)
- Kept golang.org/x/term v0.37.0 (required for stdin/stdout pipeline)
- Added fsnotify v1.9.0 from watch mode feature
- Reorganized dependencies after go mod tidy

All tests passing after merge.
