On ESP32-C3 with USB CDC, Serial.printf() blocks indefinitely when USB
is not connected. This caused device freezes when booted without USB.
Solution: Call Serial.setTxTimeoutMs(0) after Serial.begin() to make
all Serial output non-blocking.
Also added if (Serial) guards to high-traffic logging paths in
EpubReaderActivity as belt-and-suspenders protection.
Includes documentation of the debugging process and Serial call inventory.
Also applies clang-format to fix pre-existing formatting issues.
Move cachedRenderer, cachedMappedInput, and cachedSection declarations
into the DICTIONARY action block where they're actually used, addressing
cppcheck variableScope warnings.
- Fix ignored return value in TxtReaderActivity
- Remove unused variables across multiple files
- Add const correctness to DictionaryMargins and EpubReaderActivity
- Replace inefficient substr patterns with resize+append
- Use STL algorithms (find_if, any_of, copy_if, transform) where applicable
- Remove dead sync placeholder code in EpubReaderChapterSelectionActivity
- Add cppcheck suppression for ValueFlow analysis limitation
Resolves all low, medium, and high severity cppcheck defects.
The setup-python action has hardcoded paths that fail on self-hosted
macOS runners. Use system Python directly instead.
Also simplified clang-format step to use system version if available.
Adapt GitHub Actions workflows for self-hosted Gitea instance:
- CI workflow with PlatformIO build, cppcheck, and clang-format
- PR title format checker using conventional commits
- Release workflow for tagged builds
Keeps original .github/workflows/ for upstream compatibility.
Adds bookmark functionality with persistent storage, quick menu for
in-reader actions, Search tab with character picker, and unified
tab bar navigation across all library tabs.
Includes:
- BookmarkStore and BookmarkListActivity for bookmark management
- QuickMenuActivity for in-reader quick actions
- Reader bookmark integration with visual indicators
- Enhanced tab bar with scrolling, overflow indicators, and cursor
- Search tab with character picker and result navigation
- Consistent tab bar navigation (Up from top enters tab bar mode)
Adds Search tab to MyLibraryActivity with character picker for building
search queries, result navigation with long press jump-to-end support,
and Bookmarks tab integration. Implements consistent tab bar navigation
across all tabs - pressing Up from top of any list enters tab bar mode
with visible cursor indicators, Left/Right switches tabs, Down enters
list at top, and Up jumps to bottom of list.
Tab bar now scrolls to keep selected tab visible when content overflows.
Adds triangle overflow indicators and optional bullet cursor indicators
around the active tab for visual focus feedback.

Cherry-picked from upstream PR #404 with conflict resolution:
- Replaced flaky TCP-based Calibre wireless with WebSocket-based transfer
- Added OPDS authentication support (username/password in settings)
- Renamed "Calibre Library" to "OPDS Browser" in home menu
- Added UDP discovery for Calibre plugin communication
- Merged user's custom settings (customFontIndex, fallbackFontFamily, pinnedListName)
- Applied vTaskDelay cleanup after task deletion
- Kept existing "Calibre Settings" menu item (skipped KOReader Sync per preference)
Fixes issue #334 (Calibre wireless transfer not working)
Manual implementation of upstream PR #525
Added flushPartWordBuffer() function and call it before <br/> handling
to fix issue where preceding word was incorrectly wrapped to new line
