IFAKA 73d1839ddd fix: add bounds checks to Epub getter functions (#82) ... ## Problem Three Epub getter functions can throw exceptions: - `getCumulativeSpineItemSize()`: No bounds check before `.at(spineIndex)` - `getSpineItem()`: If spine is empty and index invalid, `.at(0)` throws - `getTocItem()`: If toc is empty and index invalid, `.at(0)` throws ## Fix - Add bounds check to `getCumulativeSpineItemSize()`, return 0 on error - Add empty container checks to `getSpineItem()` and `getTocItem()` - Use static fallback objects for safe reference returns on empty containers Changed `lib/Epub/Epub.cpp`. ## Test - Defensive additions - follows existing bounds check patterns - No logic changes for valid inputs - Manual device testing appreciated		2025-12-21 13:36:30 +11:00
