feat: implement individual file commits and improved file processing

- Change file operations from bulk processing to individual saves
- Commit each file immediately after write/delete/rename/search-replace operations
- Add detailed commit messages for each individual file operation
- Maintain proper error handling for git operations
- Show progress for each file operation individually
- Remove terminal command display from chat UI (silent execution)
- Improved terminal command routing based on chat mode

This provides granular control over file changes with individual commits for each operation.
