Proofing Gallery 0.8.0

• keep large custom-domain histories bounded with status-scoped cursor pages,
  server-side search, responsive incremental loading, and in-place operations
• register periodic maintenance through Nextcloud app metadata so application
  requests no longer reset cron timestamps or trigger daily jobs repeatedly
• make schema-dependent lifecycle and gallery-list backfills resumable after
  upgrades, retry failures from a persisted cursor, and report their state in
  native setup checks and operational health
• harden Calendar, Deck, and Talk review links against duplicate or orphaned
  resources and distinguish the stable agent API from the experimental Context
  Agent module in capabilities
• add a checksummed public-release upgrade baseline, full privacy-purge and cron
  regression coverage, larger scheduled scaling fixtures, and live optional-app
  integration CI
• pin the persistent Studio environment by platform digest while keeping the
  disposable development stack on current image tags; add safe refresh and
  diagnostic workflows that preserve volumes and never migrate implicitly
• resolve release-script CodeQL findings, enforce Node 24.11 before frontend
  gates, and update actionable transitive JavaScript security fixes
• reorganize owner projects into deep-linkable Overview, Photos, Cull, Design,
  Share, Review and secondary workspaces, with client results shown before
  configuration and legacy links normalized automatically
• refine the Editorial Darkroom with a focused loupe/inspector split, deliberate
  tap-to-toggle and swipe navigation, and viewport-safe desktop and mobile chrome
• add deep-linkable administration categories, live operational health refresh,
  and a shared mobile-safe Save/Discard bar for administrator and personal settings
