df321b8832 fix(jobs): make TTS segment cache invalidation non-blocking in parsePdfJob
Move TTS segment cache invalidation to a fire-and-forget promise after
document update to prevent cache errors from blocking parse readiness.
Log warnings for both cache invalidation failures and warnings, but do not
interrupt the main job flow. This improves job robustness and avoids
unnecessary failures due to cache issues.

b6be71e3b1 refactor(types,api): centralize PDF and TTS type exports to compute-core/types
Move and re-export all PDF parsing and TTS-related types from
@openreader/compute-core/types, eliminating local type duplication.
Update imports throughout the codebase to use the new centralized type
module. Remove obsolete worker-contract file and update tsconfig paths
and compute-core exports for the new types entry point. Refactor API
routes and job logic to use the new type imports and shared parse-state
healing utility. This streamlines type management and improves
consistency between compute and app layers.

09e8898683 feat(pdf,config): implement stale parse-state healing and unify op stale window config
Introduce automatic healing for stale PDF parse states in API routes. Add
`isDocumentParseStateStale` utility and use a shared `COMPUTE_OP_STALE_MS`
environment variable (with config getter) to control the stale window for both
worker op replacement and app-side parse-state healing. Update documentation and
environment variable references to reflect new config.

Enables automatic marking of stuck parses as failed, improving reliability and
retry behavior in distributed compute environments.

bf139d9a67 refactor(tts): ensure timeout cleanup and validate remote voice payloads
Make voice-fetching more robust by always clearing the request timeout and stricter type-checking of remote data.

- move clearTimeout into finally blocks for Deepinfra and custom OpenAI voice fetches to guarantee the timeout is cleared on success, failure, or abort
- validate that custom endpoint returns an array of strings before accepting voices; otherwise fall back to defaults

This reduces potential timer leaks and avoids accepting malformed voice lists from custom endpoints.

09944ec4e4 refactor(audiobooks,tts,config): tighten abort handling, progress accounting, equality checks, and voice fetch timeout
Improve robustness across audiobook pipeline, TTS catalog, and preferences comparison.

- audiobooks: centralize abort creation with createAudiobookAbortError and replace repeated ad-hoc throws with it; avoid reprocessing non-completed chapters when collecting existing indices; update progress accounting by advancing processedLength and emitting onProgress after saving a chapter.
- tts: add a 10s AbortController timeout when fetching custom OpenAI voices, wire the signal to fetch, and ensure the timeout is cleared on success or failure; fall back cleanly when endpoint doesn't support voices.
- config: harden deepEqual by checking mismatched array vs object shapes early to avoid incorrect comparisons.

No user-visible behavior changes besides improved cancellation, progress reporting, and more resilient remote voice discovery.

97dba6d987 refactor(tts,audiobook,tests): centralize TTS catalog, harden epub & UI flows
- Move TTS provider resolution and voice-fetch logic into shared catalog and make
  remote fetches more resilient (timeouts, abort handling, baseUrl normalization,
  treat explicit empty custom-openai responses as valid).
- Add continuation guard to TTS feature set and update API voices endpoint error
  logging to better surface auth/session failures.
- Extract and stabilize ebook pipeline and epub adapter:
  - Cache prepared EPUB chapters to avoid repeated parsing and handle missing/empty
    chapter titles safely.
  - Fail early when created chapter lacks a bookId.
- Improve config/preferences handling:
  - Replace JSON stringify comparisons with a deepEqual utility to compare defaults.
  - Tighten ConfigContext effect dependencies and consolidate synced preference
    queuing logic to include additional keys.
- Harden end-to-end test helpers and unit tests:
  - Make settings dialog dismissal deterministic (use Enter/Escape and explicit
    visibility/enabled checks) and simplify upload retry behavior.
  - Add unit test to ensure custom-openai empty voice lists are preserved.

Why: Reduce runtime and test flakiness, centralize TTS logic for easier maintenance,
and make EPUB processing and preference diffing more robust. Breaking changes: none.

d6ae2baa6f refactor(tts,config,audiobook): centralize TTS provider catalog and extract audiobook pipeline
- Introduce a shared tts-provider-catalog to centralize provider/model/voice defaults
  and feature flags (supportsTtsInstructions, providerSupportsCustomModel, resolveProviderModels,
  getDefaultVoices, etc.). Replace ad-hoc provider logic across server and client with catalog calls.
- Replace inline voice/model UI logic in SettingsModal, AudiobookExportModal, TTSContext,
  generate server code, and voice hook to use catalog helpers (resolveTtsSettingsViewModel,
  supportsTtsInstructions, getDefaultVoices).
- Extract audiobook generation responsibilities into a small client-side pipeline:
  - Add createEpubAudiobookSourceAdapter and createPdfAudiobookSourceAdapter adapter modules
    to prepare chapters from EPUB/PDF sources.
  - Add runAudiobookGeneration and regenerateAudiobookChapter pipeline functions to handle
    chapter preparation, progress tracking, request header construction, and retry/abort behavior.
  - Wire adapters/pipeline into EPUBContext and PDFContext to simplify and centralize audiobook flow.
- Move config preference helpers out of ConfigContext into dedicated client modules:
  - buildSyncedPreferencePatch (lib/client/config/preferences.ts)
  - applyConfigUpdate and getVoicePreferenceKey (lib/client/config/updates.ts)
  - Use these helpers in ConfigContext to keep update logic small and testable.
- Add TTS settings view model resolver (lib/client/settings/tts-settings.ts) and tests
  for the tts-provider catalog and config helpers (tests/unit/tts-provider-catalog.spec.ts).
- Minor usages updated: AudiobookExportModal, SettingsModal, useVoiceManagement, TTSContext,
  server tts generation, and various context files to consume the new modules.

Why: Reduce duplication, improve testability, and separate concerns for provider metadata,
UI view-model logic, and audiobook generation flow. Breaking changes: none.
