feat: OneNote-style notebooks, text fonts, and page navigation
Add notebook.json containers with multi-member pages, fix PDF text
editing (size/bold/drag/double-tap), index SidecarText in search, and
share keyboard page shortcuts plus a PDF scrubber.

// Round-trips a BadnoteSidecar containing per-page strokes + highlights +
// bookmarks + scratch-links (each with its own scratchpad of InkStrokes),
// asserting the re-parsed model equals the original. Verifies the sidecar reuses
// the existing EditorStroke / InkStroke / ScratchLink / Bookmark JSON shapes and
// that the schema `version` field survives.
