Adds 4 read-only Plex tools using a new plex_get helper that sends
X-Plex-Token as a query param and Accept: application/json:
- plex_library_sections: per-section item counts
- plex_on_deck: in-progress items across all libraries
- plex_watch_history: recent watches with user-name resolution via /accounts
- plex_recently_added: latest additions across sections
Token sourced from Plex registry on Darrow (HKU per-user hive). Stored
in service_configs.plex. Plex paginated counts require BOTH
X-Plex-Container-Start and X-Plex-Container-Size in query string to
return totalSize — dropping Start makes Plex return the full library.
Pirate catalog: 20 → 24 tools.
