feat: seamless auto-update via electron-updater, multi-select filters, session restore

- electron-updater wired with Gitea API discovery: setFeedURL dynamically
  per release (Gitea 1.24.7 lacks /releases/latest/download/ shortcut).
  Differential download via .blockmap saves ~70 MB per patch. Renderer
  banner shows states: available → downloading X% → ready. User clicks
  "Установить и перезапустить" → quitAndInstall replaces files + relaunches.
- Multi-select filters per user spec: genres AND (TMDB with_genres comma-
  joined), countries OR (pipe-joined into with_origin_country /
  with_original_language), years OR (fan-out one request per year, merge
  by id since TMDB has no discrete-year OR). Rating stays single threshold.
- Session persistence: openedSession {tabs, activeName} saved to config
  on tab create/show/hide/remove/in-app navigation, plus before-quit.
  Restored after did-finish-load via ipcMain.emit('create-view',...) per
  tab. Survives auto-update relaunch — bring user back to the same page.
- electron-builder publish config (generic provider) so latest.yml is
  generated during build.
