Move cohesive method groups out of the monolithic Application class
(js/app.js, ~10K lines) into five coordinator modules under js/app/:
- feedCoordinator: feed registration, runtime building, refresh,
video loading, URL-health helpers, and feed telemetry
- playbackCoordinator: URL-first + magnet fallback pipeline, probing,
torrent status intervals, and video timestamp resolution
- authSessionCoordinator: signer lifecycle, profile switching,
relay/block/wallet management, and cleanup
- modalCoordinator: modal open/close, view-count subscriptions,
watch-history metadata, and playback logging
- moderationCoordinator: moderation settings, video decoration,
override/block/hide action routing
Each coordinator factory receives injected dependencies instead of
importing globals. Application retains thin delegator methods so all
public call-sites remain unchanged. Coordinator initialisation is
idempotent (via _initCoordinators) and supports both constructor-based
and Object.create()-based instantiation used by test harnesses.
All existing unit tests, lint checks, and syntax validation pass.
