* Improved error handling and state management for Cloud TTS in `TtsService` and `TtsPlaybackManager`.
* Improved TTS voice selection UI and sample playback logic.
* Updated `TtsUtils` and `TtsService` to remove `chunkIndex` from TTS cache filenames. Refined the cache file naming convention to rely on text and speaker hashes, and updated the cache file filter logic to correctly identify speakers in both legacy and new filename formats.

* Improved locator logic and block traversal in `BookPaginator`.
* Updated AI features and Cloud TTS logic.
* Added manual clear and auto-reset functionality for AI summaries and recaps

* Restricted TTS mode to BASE in OSS flavor and fixed TTS mode persistence in PDF viewer
* Bump version to 1.0.43(44)
* Refactored the EPUB reader to use localized string resources instead of hardcoded strings across multiple components.
* Refactored the PDF viewer and annotation components to use centralized string resources instead of hardcoded text.
* Updated `strings.xml` with extensive translation hints and localization metadata.
* Optimized PDF tile rendering performance and quality.
* Added support for adjusting TTS voice speed and pitch.
* Updated the TTS settings UI and playback logic to support real-time parameter adjustments.
* Added horizontal scrolling to the PDF viewer bottom toolbar and updated tool arrangement to use fixed spacing.
* Refined cross-page selection and text extraction in `PaginatedReader`
* Updated EPUB reader styling logic to refine typography and layout controls.
* Bump version to 1.0.42(43)
* Improved local folder sync and file management by migrating sidecar metadata to a dedicated subfolder and enhancing book ID stability.
* Optimized folder sync and increased synced folder limits.
* Added support for managing active tabs in the `HomeScreen`.
* Added support for strict file type filtering when picking documents.
* Added a "Remove Edge Padding" option in "Visual Options"
* Added support for paragraph gap settings in the EPUB vertical reader.
