feat+test+docs: D46 — owner-vs-guest gating for /health + X-OLP-Fallback-Detail (Phase 2) (#22)

* feat+test+docs: D46 — owner-vs-guest gating for /health + X-OLP-Fallback-Detail (Phase 2)

Third Phase 2 implementation D-day. Closes ADR 0007 § 10 acceptance
criteria #4 (/health payload trimming for non-owner) + #5
(X-OLP-Fallback-Detail emission gating per fallback_detail_header_policy).
Phase 2 server surface now fully gated end-to-end; remaining D-days
are keygen CLI surface (D47+) and Phase 2 close (v0.2.0, maintainer-
triggered).

server.mjs handleHealth identity-aware payload per § 7.1:

  - Auth gate at top — 401 for unauth + allow_anonymous=false; 200
    with trimmed { ok, version } for non-owner; 200 with full payload
    for owner.
  - Trim controlled by _authConfig.owner_only_endpoints — operator
    removing /health from the list reverts to v0.1.1 full-payload-to-
    everyone (opt-out knob).
  - touchLastUsed fires on res.on('finish') for filesystem identities;
    no audit row on /health (high-volume monitoring; out of scope at
    Phase 2 per § 8).

server.mjs withFallbackDetailHeader identity-aware emission per § 7.2:

  - New shouldEmitFallbackDetailHeader(olpIdentity) helper reads
    _authConfig.fallback_detail_header_policy:
      'owner_only' (default) → emit only to owner
      'all'                  → emit unconditionally (v0.1.1 opt-back-in)
      'none'                 → suppress unconditionally
  - olpIdentity null on pre-auth paths → emit (preserves D40 v0.1.1
    behaviour for pre-auth errors where identity is unknown).
  - withFallbackDetailHeader signature gains 3rd `olpIdentity` arg;
    both call sites in handleChatCompletions updated.

Test surface — Suite 21, +9 tests; +1 in Suite 20 (20m); 515 → 524:

  20m: /health with no auth + allow_anonymous=false → 401
       (consistency with /v1/*)
  21a-d: /health payload trimming (criterion #4): anonymous trimmed;
         guest trimmed; owner full; owner_only_endpoints: [] opts out
  21e-h: X-OLP-Fallback-Detail emission gating (criterion #5):
         owner_only + guest → header absent
         owner_only + owner → header present + valid JSON
         'all' + guest → header present (v0.1.1 opt-back)
         'none' + owner → header absent (full suppression)
       Tests use 2-hop chain anthropic→openai with anthropic primary
       failing to produce non-empty fallbackDetail for header content.

Test-mode setup updated:

  Global __setAuthConfig({ allow_anonymous: true }) extended to also
  pass owner_only_endpoints: [] + fallback_detail_header_policy: 'all'
  so pre-D46 tests (Suite 18, F5 /health tests, D40 fallback-detail
  tests, etc.) continue to pass; Suite 21 overrides per-case.

DOCS:

  - AGENTS.md: lib/keys.mjs marker updated to reflect D46 ship; impl-
    status-note + shipped-set updated.
  - README.md: Implementation Status row + Known limitations "Multi-key
    auth" note rewritten to reflect D46 ship + remaining keygen CLI.
  - CHANGELOG.md: D46 entry under Unreleased per release_kit overlay.

AUTHORITY:

  - ADR 0007 §§ 7.1 + 7.2 implementation contracts + § 10 criteria
    #4 + #5 covered.
  - ADR 0004 Amendment 5 (D40 — "Phase 2 will re-introduce owner-vs-
    non-owner gating when lib/keys.mjs lands"): this D-day fulfils the
    deferral.
  - CLAUDE.md release_kit overlay phase_rolling_mode — under Unreleased.
  - Standing autopilot grant (~/.cc-rules/memory/auto/
    standing_autopilot_phase_2.md in cc-rules bf0ed9a).

Verified: 524/524 pass via npm test (no regression in 515 pre-D46
tests; 9 new Suite 21 tests + 1 new Suite 20m test all green).

* docs: D46 fold-in — opus reviewer P3 polish (constant import + comment tighten)

Fresh-context opus reviewer (PR #22) returned APPROVE_WITH_MINOR with 2 P3
findings, both trivial polish.

- server.mjs imports gain ENV_OWNER_KEY_ID from lib/keys.mjs (already
  used the namesake ANONYMOUS_KEY_ID import). handleHealth touchLastUsed
  guard now uses the imported constant for SPOT discipline.
- handleHealth audit-deferral comment tightened: removed the "§ 8 schema
  doesn't mandate auditing" phrasing (overstates the ADR — § 8 doesn't
  enumerate paths); replaced with the operational rationale (high-volume
  noise, no observability value until Phase 3 Dashboard).

No behaviour change. 524/524 tests pass (verified locally).

Authority: PR #22 fresh-context opus reviewer findings.
