Add MPV_REUSE_INSTANCE key to the electron backend store service and
include mpvReuseInstance in the shared settings interface so the new
boolean setting is persisted and available across renderer and main
processes.
Also update English i18n JSON formatting and expand the HOME section
translations (reformatting and adding nested playlist-related keys)
to ensure the UI strings remain consistent after changes.
MPV/VLC launch and playlist auto-update from the Electron preload
and migrate Tauri invoke calls to use the exposed window.electron API.
- Add openInMpv, openInVlc and autoUpdatePlaylists to the preload API,
forwarding parameters to ipcRenderer for native handling.
- Replace tauri invoke('open_in_mpv') and invoke('open_in_vlc') calls
with window.electron.openInMpv / openInVlc in tauri.service to use the
unified Electron IPC surface.
- Replace file-based AUTO_UPDATE_PLAYLISTS handling with a call to
window.electron.autoUpdatePlaylists and remove legacy file parsing
code (now commented) so the main process owns playlist refresh logic.
- Import shared AUTO_UPDATE_PLAYLISTS/Playlist types into preload.
This centralizes native player launching and playlist updates through the
preload IPC bridge, simplifying web service code and moving file I/O to
the native/main layer for better security and separation of concerns.
