release(phase-1-cleanup): v0.1.1 — pre-Phase-2 batch (D35-D42)

Phase 1 cleanup release per CLAUDE.md release_kit.phase_rolling_mode
policy. Closes 16 of 17 pre-Phase-2 GitHub issues; #16 stays OPEN as
v1.x tracker with design ratified in ADR 0005 Amendment 8.

Bumps package.json from 0.1.0 → 0.1.1. Promotes CHANGELOG "Unreleased"
section to "## v0.1.1 — 2026-05-25" with full D35-D42 entries
(backfilled D35/D36/D37 entries per cold-audit round 7 Finding 1) and
final cleanup batch summary covering all 8 D-day commits that landed
on `main` between 2026-05-24 and 2026-05-25.

Tag v0.1.1 will be pushed after this commit lands and CI is green.
release.yml auto-creates the GitHub Release from the CHANGELOG v0.1.1
section (extracted via awk pattern match on `## v0.1.1` heading).
D37's phase_rolling_mode gate now passes because Unreleased is
sentinel-only after this commit.

**What v0.1.1 delivers (D35-D42):**

- D35 — streaming empty-stream headers (#9) + truncation marker (#10)
  + irVersion strict check (#11) + alignment.yml scripts/** removal
  (#12) + X-OLP-Latency-Ms uniform audit (#4)
- D36 — cache_control partial-noop log (#2) + ADR 0002 filename
  correction (#5) + mistral A5 flip (#6) + /v1/models alias governance
  (#13) + cache_control determinism test (#14) + anthropic v2.1.89
  transcript artifact (#15)
- D37 — release.yml phase_rolling_mode CI gate (#17)
- D38 — maxConcurrent runtime enforcement + new CONCURRENCY_LIMIT
  hard trigger (#1)
- D39 — CacheStore.delete + cache_evicted_truncated log + sticky-
  cache regression test + SPAWN_TIMEOUT asymmetry ADR (#3)
- D40 — X-OLP-Fallback-Detail debug header + per-hop tuple collection
  + 4KB cap + RFC 7230 non-ASCII escape (#7)
- D41 — X-OLP-Provider-Used chain-origin semantics documented (#8)
- D42 — streaming singleflight v1.x design ADR + multi-layer
  safeguards (issue #16; STAYS OPEN as v1.x tracker)

**Test growth:** 416 (v0.1.0) → 468 (v0.1.1). +52 tests across the
8 D-day batch. All 468 pass at the release-commit head.

**Cold-audit cycle:** 1 final round (round 7) over D35-D42 + v0.1.0
state. Result: PASS_WITH_MINOR with 4 findings (1×P3 + 3×P4).
- Finding 1 (P3 CHANGELOG missing D35/D36/D37) — FIXED in this commit
  via backfill.
- Finding 2 (P4 ADR 0005 Amendment 8 "Amendment 1/3/5" notation
  ambiguity) — FIXED in this commit (replaced with explicit
  § Decision body item-1 + Amendment 3 + Amendment 5 wording).
- Finding 3 (P4 ADR 0005 Amendment 8 Context paragraph cites line 811
  but actual branch is at lines 817-823) — FIXED in this commit
  (Context paragraph now points at lines 817-823 with the TODO anchor
  at ~810 as the navigable landmark).
- Finding 4 (P4 ADR 0002 missing Amendment 2 — pre-existing gap)
  — FIXED in this commit (added explanatory note under the
  Amendments heading explaining the gap is intentional and load-
  bearing).

No P1 or P2 findings.

**Phase 1 cleanup release_kit checklist** (per CLAUDE.md):

  fixed in this commit)

  #16 stays OPEN as v1.x tracker with design ratified
- [x] Issue #16 status comment posted (D42 commit b0c080d)
  referencing ADR 0005 Amendment 8 design ratification
- [x] CHANGELOG "Unreleased" promoted to "## v0.1.1 — 2026-05-25"
  with D35-D42 entries (including backfilled D35/D36/D37)
- [x] package.json bumped from 0.1.0 → 0.1.1
- [x] docs/v1x-roadmap.md created at D42 — 7 deferred items with
  code anchors + GitHub-issue cross-refs + concrete start triggers
- [x] Editorial findings 2/3/4 from round 7 folded into this commit
- [ ] Tag pushed (next step in this PR's lifecycle)
- [ ] release.yml triggered + GitHub Release created (auto on tag
  push; D37 phase_rolling_mode gate will pass because Unreleased
  is now sentinel-only — gate dry-run verified locally)

**Known limitations carried to v1.x:** full list with code anchors
+ start triggers in docs/v1x-roadmap.md. The 7 items are:
1. Streaming-path singleflight (issue #16, ADR 0005 Amendment 8)

3. Soft-trigger reactivation (ADR 0004 Amendment 2)
4. /health activeSpawns integration (ADR 0002 Amendment 6)
5. Provider-level cacheKeyFields mask (ADR 0005 Amendment 7)
6. Streaming-path SPAWN_FAILED salvage
7. D40 AUTH_MISSING tuple test coverage
