## Summary * **What is the goal of this PR?** Add a "Continue Reading" feature to improve user experience when returning to a previously opened book. * **What changes are included?** - Add dynamic "Continue: <book name>" menu item in Home screen when a book was previously opened - File browser now starts from the folder of the last opened book instead of always starting from root directory - Menu dynamically shows 3 or 4 items based on reading history: - Without history: `Browse`, `File transfer`, `Settings` - With history: `Continue: <book>`, `Browse`, `File transfer`, `Settings` ## Additional Context * This feature leverages the existing `APP_STATE.openEpubPath` which already persists the last opened book path * The Continue Reading menu only appears if the book file still exists on the SD card * Book name in the menu is truncated to 25 characters with "..." suffix if too long * If the last book's folder was deleted, the file browser gracefully falls back to root directory * No new dependencies or significant memory overhead - reuses existing state management
