docs(macroplan): mark v0.5 delivered, close slice-4 on-device gate

All four v0.5 slices are done and device-verified: the prefs round-trip is
confirmed both directions (boot-read + on-device palette edit -> push flipped
line_numbers on origin), and the slice-3 delete fix is recorded as confirmed on
device. Descoped items (buffer close, grey-Publish-in-Local cue, multi-file
publish count) noted, not blocking delivery.
