Replace the single free-text note per lesson with a list of timestamped
note entries, migrated transparently from the old format. Adds a
floating notes panel on the lesson page with an always-reachable
quick-capture bar (press N to pause and jump in), inline edit/delete,
click-to-seek timestamps, and a live "Saved Xs ago" indicator. Notes
Hub, the study guide export, and the Outline push all updated to
render multiple timestamped notes per lesson.
