feat: auto-save audiobook to Rehearser IndexedDB + Edit in Rehearser (v1.12.6)

- Casting completion auto-saves to Rehearser IndexedDB (same format
  as script rehearsals). Manual speaker corrections in the cast view
  debounce-save after 1.5s.
- rehId tracked across session (stored in localStorage draft) so
  updates go to the same record instead of creating duplicates.
- Voice assignments made in Script Rehearser survive an auto-update:
  only script text and emotions are overwritten; voice/instruct/soul
  are merged from the existing record.
- "Edit in Rehearser" button in the completed cast footer opens the
  saved record directly in Script Rehearser, ready for voice casting.
- Expose rehDbGetById + rehLoadRecord globally from rehearser.js.

+## [1.12.6] — 2026-06-27
+
+### Added
+- **Audiobook auto-saves to Script Rehearser**: when casting completes, the result is automatically written to the Script Rehearser IndexedDB (same format, same library). The record is updated — not duplicated — whenever speaker corrections are made in the cast view. The record appears immediately in Script Rehearser → Library.
+- **"Edit in Rehearser" button**: replaces "Review & cast" in the completed cast panel. Opens the saved record directly in Script Rehearser with all speakers, voices, and page markers intact, ready to assign voices and synthesise.
+- Voice assignments made in Script Rehearser are **preserved** when the audiobook auto-saves again (only the script text and emotions are overwritten; voice/instruct/soul fields survive the update).
