ADR: introduce docs/history/, merge 0011+0018, prune migration cruft

- CLAUDE.md: add ADR Lifecycle subsection (superseded → docs/history/,
  immutable numbering, no renumber)
- ADR-0011: merge ADR-0018 content as "Address Model: LA" section
  alongside PA / VA; status notes VA model is currently implemented
- ADR-0018 / 0029 / 0031: moved to docs/history/ with status updates
  (0018 merged into 0011, 0029 superseded by 0032, 0031 absorbed
  into 0001 rev 2)
- ADR-0019: rewrite Context as PE-HBM connectivity decision
  (self-contained, no LA model framing)
- ADR-0019/0020/0021/0023/0025/0027: Status Proposed → Accepted
  (code verified) and prune Implementation Notes / Affected files /
  Test strategy / "현재 상태" sub-sections describing pre-impl state
- ADR-0024/0026: same migration-flavor cleanup; 0026 also drops D6
  Migration and D8 docs-update sub-decisions
- ADR-0030: status simplified (blocker ADR-0031 now superseded)
- SPEC.md: R10 + §0.2 reflect PA / VA / LA model names
- ADR-0008/0012/0013: refresh ADR-0011 subtitle in Links
