Add update_channel setting (stable/canary) to Settings with UI toggle. Stable channel uses Tauri updater plugin; canary fetches latest-canary.json and opens GitHub release page for manual download. Add useFeatureFlag() hook with localStorage overrides and compile-time defaults (no remote dependencies). Add release-canary.yml CI workflow for canary branch builds. Update stable workflow to preserve latest-canary.json on GH Pages. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
