release: 0.66.0 — E5 Plex epic (scoped search, HU localization, toolbar/header)

Ships the E5 sprint stack (S1–S7): field-scoped Plex search + typeahead, cast &
crew pages, the HU-overlay Hungarian metadata + language-aware serving, the
IMDb/audience rating split, the toolbar relocation, and the narrow/mobile header
fix — plus the underlying Plex-module refactors (feedquery/plex.cards/plex.query
extraction, db.query→2.0 select).

- VERSION 0.65.2 → 0.66.0
- releaseNotes.ts: 0.66.0 user-facing entry
- prettier-format the E5-touched frontend files (release hygiene)

Merged main (0.65.2 download-gc hotfix) in first; no code conflicts (E5 is
Plex-only, the hotfix was notifications/downloads).
