Changelog

[v1.4.1] - 2026-01-03

Asynchronous file scanning: UI remains responsive during large scans, with progress updates and cancellation support.
Enhanced status display:
- Split status into two rows with better visual hierarchy
- "Marked for deletion" line shown only when files are marked (bold formatting)
- Dynamic text wrapping for long folder paths with reserved 2-line height
- Status container now at top of window for better visibility

Refactored main application to use a package structure; removed legacy monolithic files and added a new launcher (run.py), supporting python -m rom_duplicate_manager.
Improved "All Files" filter: now ignores images unless "Scan Images" is selected; clarified tooltip for "Scan Images".
Added comprehensive type hints to event handlers and UI components for better code clarity and editor support.
Improved UI layout and workflow:
- Reorganized button layout for more intuitive flow
Enhanced sorting behavior:
- Duplicate groups (multiple files) now always appear at top of list
- Unique groups (single file) appear below duplicates
- Both sections maintain selected sort order (filename/path, ascending/descending)
- Sort resets to filename ascending on each new scan
- Marked items (keep/delete) stay at top within each group

Restored correct dual behavior for "Scan Images" (image inclusion and orphan cleanup).
Minor bugfixes and improved error handling in scanning and UI.
Sort state properly tracked for user-initiated vs programmatic sorts
Fixed method signature inconsistencies in file list module
