比照 pwa-next 已完成的重構，新增 services/{bookService,bookmarkService,progressService,
annotationService}.ts 封裝本機 storage CRUD；原本 store/useAnnotationStore.ts（Zustand +
模組級 subscribe 自動持久化，帶有排序陷阱）整個移除，改成 hooks/reader/useAnnotations.ts
（useState/useCallback），useLibrary.ts／useBookmarks.ts／useAnnotationPopups.ts／
NotePanel.tsx 改為呼叫對應 service 或透過 props 傳遞 annotations。
同時修正三個過程中發現的問題：
- 文字選取終點剛好落在下一段落開頭時，epub.js 算出的 CFI 還原成 Range 畫底線會塌縮成
0 寬度、完全看不到；改為偵測後收斂選取終點、用 contents.cfiFromRange() 重新產生 CFI。
- 書籤清單跳轉後不再自動關閉桌面版側邊欄，比照 pwa-next 同一個修法。
- 翻頁進度存檔改用 debounce + 離開時 flush，並明確跳過「程式自己呼叫 display(savedCfi)
還原造成」的 relocated 事件，避免版面穩定期間的雜訊事件覆蓋使用者真正的閱讀進度
（仍有極少數情況下可能有一頁落差，待後續持續觀察）。
新增 constants/debug.ts 集中管理 DEBUG_ANNOTATIONS／DEBUG_PROGRESS 除錯開關，目前為
開啟狀態，用於協助後續繼續追蹤翻頁進度的殘留問題。

Wait for the free limit to reset to keep reviewing this public repository. How can I continue?After more reviews become available, a review can be triggered using the To avoid repeated limits, reduce automatic review volume by pausing incremental auto-reviews earlier, using label-based review opt-in, excluding WIP or generated PR titles, or requesting reviews manually when the PR is ready. If your team needs uninterrupted high-volume reviews, an organization admin can enable usage-based reviews. How do review limits work?CodeRabbit enforces per-developer PR review limits for each organization. Most developers receive the normal plan review availability. For paid Pro and Pro+ PR reviews, CodeRabbit uses adaptive limits for sustained high-volume activity. When a developer's recent PR review activity reaches the 95th percentile or higher among CodeRabbit users, additional reviews become available more gradually as earlier reviews age out of the rolling window.

📝 WalkthroughWalkthroughThe renderer adds local persistence services and replaces annotation-store access with hook-managed state. Reader initialization and progress saving now use services and refs. Selection spillover handling, annotation diagnostics, bookmark persistence, and debounced TTS rate changes were also updated. ChangesRenderer local persistence refactor

Estimated code review effort: 4 (Complex) | ~45 minutes Merge Risk: 🟠 High · up to This PR changes reader persistence, annotations, and playback flows, but the current version can lose annotation updates, retain notes for deleted books, leave orphaned EPUB data after a save failure, restart newer speech unexpectedly, and crash on malformed stored annotation data. These concrete data-integrity and availability risks should be fixed before merging. Sequence Diagram(s)sequenceDiagram

Inline comments:
In `@CLIENT_SERVICE_HOOK_REFACTOR.md`:
- Around line 16-21: Update the renderer progress/status entry around the
section covering lines 162-170 so it matches the recorded state: renderer local
data-layer work is already committed and pushed as f294026, rather than still
uncommitted. Keep the existing note about the pagination-progress issue and
ongoing verification intact.
In `@renderer/src/constants/debug.ts`:
- Around line 4-8: Set the default values of DEBUG_ANNOTATIONS and
DEBUG_PROGRESS to false in the constants module, so verbose reader diagnostics
remain disabled unless explicitly enabled through debug configuration.
In `@renderer/src/hooks/reader/useAnnotations.ts`:
- Around line 34-70: Update persist, addAnnotation, removeAnnotation,
updateColor, and updateNote to derive next values from annotationsRef.current
rather than the render-time annotations closure, preventing concurrent mutations
from overwriting each other. Make persist return whether local.save succeeded,
have each mutation return that success result (with addAnnotation only reporting
success when persistence succeeds), and ensure callers such as
useAnnotationPopups update EPUB annotations only after a successful mutation.
In `@renderer/src/hooks/useLibrary.ts`:
- Around line 80-88: Update removeBook to delete the removed book’s annotations
through annotationService.local, adding the corresponding annotation-service
removal operation if it does not already exist, alongside the existing
bookmarks, progress, and settings cleanup.
In `@renderer/src/hooks/useTTS.ts`:
- Around line 428-441: Capture the current generationRef value when scheduling
the rate-change debounce timer, and have its callback return if
generationRef.current has changed before restarting playback. Keep the existing
playing/current-text and remaining-text checks intact so stale timers cannot
restart a resumed utterance or chained chapter.
In `@renderer/src/services/annotationService.ts`:
- Around line 15-20: Update the load method to validate the JSON.parse result
before returning it: return the parsed value only when it is an array, otherwise
return an empty array. Preserve the existing fallback for parse failures, and
validate annotation fields as needed to safely support data from older
application versions.
In `@renderer/src/services/bookService.ts`:
- Line 24: Update saveMeta and the useLibrary.addBook flow so
localStorage.setItem failures produce a clear failure result or typed error
before the record is published; ensure callers remove the already-stored EPUB
and cover, or otherwise avoid committing UI state when metadata persistence
fails.

Disable verbose diagnostics by default.
Both flags enable high-frequency reader logs. The relocated handler also logs annotation and progress identifiers. Set these defaults to false before release and enable diagnostics only through an explicit debug configuration.

Handle metadata-write failures before publishing the record.
localStorage.setItem can throw. useLibrary.addBook stores the EPUB in IndexedDB before it calls saveMeta. If Line 24 fails, the EPUB remains orphaned without a durable library record.
Return a failure result or throw a typed error. Update callers to roll back the file and cover, or report the failure before committing UI state.
