NeoQuill v0.9.15

• Added: Canonical Transcript JSON export with engine metadata, audio
  fingerprint, quality report, segments and word timings for reproducible
  reprocessing.
• Added: XcodeGen project support so NeoQuill can be opened and run from Xcode
  without losing the SwiftPM build path.
• Changed: Beta builds stay free for all 0.9.x versions; paid license
  enforcement starts only with 1.0.0.
• Fixed: Large transcript views now page and collapse repeated runs so meetings
  with thousands of transcript rows do not freeze the app.
• Fixed: Final-STT rejects repeated hallucination transcripts before they are
  persisted as final meeting text.
• Fixed: Sparkle is embedded in the app bundle so installed builds no longer
  crash at launch because the framework is missing.
• Changed: The app surfaces its current version in the UI for support and
  tester feedback.
