chore(meta): cascade refocus — supersede v0.2 cluster, re-home backlog tree, capture workshop WIP

Governance:
- D-166 amendment (2026-06-12): outside-in build order (geo → econ-on-world →
  building templates → door boundary contracts → NPC/interiors → gameplay);
  Phase 5 ramps in parallel once outsides are walkable (gate: T-962)
- D-114/D-115/D-117/D-118/D-120 marked superseded by D-166 (inbound anchors fixed)
- D-221 amended: milestones retired, cascade-hierarchy gating is canonical
- Q-077/Q-068/Q-036 resolved (answered by events); Q-110 (scale anchoring) and
  Q-111 (live-econ coupling) opened from cascade grounding

Ticket tree (147 stray backlog tickets dispositioned):
- New parents: T-1036 (post-cascade gameplay parking), T-1037 (maintenance initiative)
- Re-homed: 15 → Phase 4 (T-750), 30 → Phase 5 (T-749), 11 → Phase 6 (T-751),
  21 → gameplay parking, 28 → maintenance; children follow their epics
- Cancelled 12 administrative shells (mirror tickets, emptied pre-cascade umbrellas,
  v0.2 pivot shell T-603); T-9/T-28 closed done; T-745 in_progress
- New grounded tickets T-1038..T-1044: inter-settlement road/rail graph, L3→L4
  dispatch threading, river-channel-anchor bug, 64m landform-repeat bug,
  region seam blending, road-entry octants, drainage re-run fix

Docs:
- CLAUDE.md cascade paragraph updated to the amended rule
- 20 v0.1-era docs/design files marked superseded with pointers;
  content-structure-canonical retitled (v0.2 label dropped)
