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- CLAUDE.md: add ADR Lifecycle subsection (superseded → docs/history/,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  (0018 merged into 0011, 0029 superseded by 0032, 0031 absorbed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- ADR-0030: status simplified (blocker ADR-0031 now superseded)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

ADR-0021: PE pipeline refactor — component separation + token self-routing

Design for refactoring pe_accel monolith into independent builtin components:
- D1: 6 independent components (scheduler, DMA, fetch_store, GEMM, MATH, TCM)
- D2: Token self-routing — scheduler only dispatches + tracks completion
- D3: done signal = simpy.Event (HW wire), data = message (queue)
- D4: Async pipeline with single FIFO feeder, command-level ordering
- D5: PE_FETCH_STORE separates TCM↔register from compute
- D6: Compute components implement _process() only, chaining in base
- D7: Topology adds pe_fetch_store + chaining edges
- D8: Existing builtin/pe_accel → builtin_legacy backup, new builtin
- D9: TileToken with plan + stage_idx for self-routing

Key decisions from review:
- No PipelineManager object — scheduler + existing ports sufficient
- PipelineContext with exactly-once completion contract
- _feed_loop singleton per scheduler, FIFO command ordering
- Intra-PE chaining: no explicit latency model
- Latency models ported from pe_accel current implementation
