fix: disable macOS mpv menu shortcuts, buffer latest subtitle IPC state

- Pass --macos-menu-shortcuts=no on Darwin so SubMiner bindings reach mpv
- Replace queued IPC listener with latest-value variant for subtitle channels
- Skip JSONC line/block comments in duplicate-key offset helpers
- Preserve configured Anki note model name in selectPreferredNoteFieldModelName
- Guard known-words deck rename against collision; add chooseKnownWordsDeckRenameValue
- Apply asCssColor on hover token CSS compat reads
