docs(02): cite D-12, D-16, D-32 in plan must_haves + record planning complete

Decision-coverage gate found three CONTEXT.md decisions structurally
implemented but not literally cited by their D-NN tags. Added one-line
must_haves entries citing each:

- D-12 (Lura as discrete gate visits, 3 beats this Season) → 02-04
- D-16 (all Lura dialogue authored in Ink, runtime via inkjs) → 02-04
- D-32 (Zustand 5 store as the Phaser↔React bridge; sim never imports
  store, CORE-10 enforced) → 02-01

STATE.md flipped from in_progress (context gathered) to ready_to_execute
with the planning summary in stopped_at.

All 24 REQ-IDs + 34 D-XX decisions now covered.
