Declared-but-empty projects persist locally (UserDefaults) until a
note carries the name, at which point the project syncs via notes as
usual. Empty declared projects can be swipe-deleted.

Notes gain an optional project (schema v4, additive). Projects derive
from note values like tags — no separate entity. Tab naming
(Projects/Categories) is a Settings choice applied across the UI.
