Add Apple Pencil support, reading plan, full-text search, and inline ink

- Apple Pencil hover cursor: previews brush size/shape before contact
- Tilt shading: tilted pen strokes widen and reduce thinning via tiltX/Y
- Two-finger undo in draw mode (non-stylus two-finger tap)
- Copy & open Claude buttons: copies study/podcast prompt then opens claude.ai/new
- Inline ink canvas in study notes (DrawCanvas embedded in Notes tab)
- Full-text search across all project notes with 300ms debounce
- Reading plan: set a book + week goal, mark chapters read from the reader
