feat: v0.1.6 - auto-refresh file list, separate reset key

- Auto-refresh: file list now checks directories every 2 seconds for new files
- r key: resets done/error/deleted file back to idle for reconversion
- f key: manually refresh the file list
- d key: removes file from list only (unchanged)
- Auto-refresh works for directories that files were loaded from
- Updated help menu and bottom bar with new keybindings
