dev: umfangreiches Refactoring, Trakt-Integration und Code-Review-Fixes (0.1.69-dev)

Core & Architektur:
- Neues Verzeichnis addon/core/ mit router.py, trakt.py, metadata.py,
  gui.py, playstate.py, plugin_manager.py, updater.py
- Tests-Verzeichnis hinzugefügt (24 Tests, pytest + Coverage)

Trakt-Integration:
- OAuth Device Flow, Scrobbling, Watchlist, History, Calendar
- Upcoming Episodes, Weiterschauen (Continue Watching)
- Watched-Status in Episodenlisten
- _trakt_find_in_plugins() mit 5-Min-Cache

Serienstream-Suche:
- API-Ergebnisse werden immer mit Katalog-Cache ergänzt (serverseitiges 10-Treffer-Limit)
- Katalog-Cache wird beim Addon-Start im Daemon-Thread vorgewärmt
- Notification nach Cache-Load via xbmc.executebuiltin() (thread-sicher)

Bugfixes (Code-Review):
- Race Condition auf _TRAKT_WATCHED_CACHE: _TRAKT_WATCHED_CACHE_LOCK hinzugefügt
- GUI-Dialog aus Daemon-Thread: xbmcgui -> xbmc.executebuiltin()
- ValueError in Trakt-Watchlist-Routen abgesichert
- Token expires_at==0 Check korrigiert
- get_setting_bool() Kontrollfluss in gui.py bereinigt
- topstreamfilm_plugin: try-finally um xbmcvfs.File.close()

Cleanup:
- default.py.bak und refactor_router.py entfernt
- .gitignore: /tests/ Eintrag entfernt
- Type-Hints vereinheitlicht (Dict/List/Tuple -> dict/list/tuple)
