Full Book now assembles from a fresh read of the canonical book metadata
(chapter order + chapter entries) instead of the renderer's in-memory
chapter array, so it always contains every chapter in the current order
and can never render from stale or partially-loaded state. The chapter
sidebar and Full Book share the same single source of truth.
Also refresh Full Book whenever book metadata loads, and extend the e2e
scenario to cover reordering to a new order, order persistence across
reopen, and delete/rename/new-empty chapters all being reflected.
Route the renderer select-all listener (previously sent but never handled) to
the active editor, and extend the e2e scenario to verify the Full Book
assembly, stats, Copy All clipboard content, and read-only select-all.
- Bind Ctrl+Shift+S to strikethrough
- Smart code toggle: fenced block for multi-line selections, inline otherwise
- Link editing: selecting an existing link now selects its URL for editing
- Route undo/redo shortcuts through IPC so CodeMirror history is used when
the editor has focus instead of Electron's native menu-role undo/redo
- Add Indent/Outdent toolbar buttons
