Ports upstream PR #1342 (feat: Add Book Info screen, richer metadata, and safer file-browser controls) with mod-specific adaptations: - Parse and cache series, seriesIndex, description from EPUB OPF - Bump book.bin cache version to 6 for new metadata fields - Add BookInfoActivity (new screen) accessible via Right button in FileBrowser - Add ManageBook menu via Left button in FileBrowser (replaces upstream hidden delete) - Guard all delete/archive actions with ConfirmationActivity (10 call sites) - Add inputArmed gating to ConfirmationActivity to prevent accidental confirmation - Safe deserialization: readString now returns bool with MAX_STRING_LENGTH guard - Add series field to RecentBooksStore with JSON and binary serialization - Add i18n keys: STR_BOOK_INFO, STR_AUTHOR, STR_SERIES, STR_FILE_SIZE, etc. Made-with: Cursor
