OpenReader Native v1.3.0

Phone narration repair and server-generated offline audio

• Fix number-only passages producing no Kokoro audio. Existing completed
  passages and the installed voice pack are preserved; resume preparation
  instead of deleting the saved narration.
• Choose Phone / offline voice or Server / save on phone under
  Prepare entire PDF audio.
• Download complete server narration and PDF timings for continuous offline
  playback, without the model pack or a server connection.
• Switch between Phone / offline, Saved server / offline, and live
  Server in the PDF's audio-source menu.
• Preserve the server's voice/blend, canonical paragraph plan and available
  word alignments. Missing word alignments are explicitly approximate.
• Keep incomplete or skipped server exports from replacing a complete recording.
• Fix a PDF-layout readiness race exposed by immediately available saved audio.

Signed ARM64 APK updates v1.2.0 without removing app data. Phone preparation
still requires the open screen; server jobs can continue while phone preparation
is stopped. All supplied documents/screenshots are synthetic. No user PDFs,
credentials, private configuration, or signing keys are distributed.

The Docker-load download image is linux/amd64, containing only the reviewed
APK, corresponding Android source and pinned voice pack. The full container
and server configuration remains in the public repository. Verify SHA256SUMS
before installation or docker load.
