Windows YouTube Stability & V2 Visual Pass

• Windows YouTube login pipeline stabilized with DPAPI cookie error classification and fallback handling.
• Floating capture v2.2 Phase 2D.3 fixes Windows crash and freeze cases in the persistent capture flow.
• YouTube extraction hardened with POT Token scoping, multi-client fallback, and fake-quality guards.
• Premium restore now surfaces backend LICENSE_NOT_FOUND instead of a generic error.
• V2 visual pass shipped across player, converter, browser, activity center, settings, support, premium, and dialog surfaces.

Reliability & Crash-Free Update

• Crash fix: home page no longer crashes when rendering imported library thumbnails — resolves the v1.6.2/v1.6.3 "No host specified in URI" crash-loop.
• Crash fix: tap-to-play / pause no longer crashes when the player is closing.
• Windows + Linux first-launch reliability: gallery-dl now downloads from a daily-built mirror with a fallback chain so an upstream-empty release cannot brick fresh installs.
• Image download is now optional at first launch — yt-dlp + ffmpeg succeed alone if a gallery-dl mirror is unreachable; users still reach the home screen.
• Telemetry: update banner show, click, and dismiss events are now recorded so adoption stalls are diagnosable instead of guessed.
• Backend release traceability: /health and /version now expose real build SHA and version.
• CI workflow: Linux artifacts are now correctly attached to GitHub releases (artifact-symmetry gate added).
• Pre-release validation: new scripts/preflight_release.sh checks workflow YAML symmetry, all binary URLs return 200, and backend release records are healthy before tagging.

Stability & Hardening Update

• Cinematic Aurora UI refresh across top nav, browser, home, premium, support, and YouTube surfaces.
• Auto-update reliability: streaming SHA-256 verify with HTTP Range resume so an interrupted update continues from the last byte.
• Supply-chain integrity: yt-dlp installs verify against upstream SHA2-256SUMS manifest before accepting the binary.
• Windows installer signing path validated end-to-end (Sectigo HTTPS timestamp, RSA-baseline gate); macOS entitlements tightened (no JIT, no unsigned executable memory).
• VidCombo migration: license-key import is now idempotent under antivirus interference; legacy folder scan covers Dropbox + Google Drive paths.
• Notification permission channel: null-guarded against pre-init calls to fix MissingPluginException on cold start.
• Keychain probe: probe-once strategy with 24h fallback cache eliminates per-launch retry spam on unsigned debug builds.
• Observability: 5 critical Sentry breadcrumbs for marker-policy, supply-chain hash, cache hit/miss, auto-update resume, secure-credential fallback.

Clipboard Radar & Aurora UI

• Clipboard Radar: auto-detect video URLs from the clipboard with rich metadata preview.
• Aurora UI: cinematic gradient variants across core destinations.
• Fixed macOS entitlement crash caused by keychain access group rejection.
• Fixed a notification channel race condition on macOS.
