feat(ci): v0.9.0 — Distribution & Expansion milestone complete

---ci---
project: ci
phase: 6
milestone: v0.9
status: complete
artifacts:
  tags: [v0.9.0]
decisions:
  - id: D-047
    decision: v0.9 theme = Distribution & Expansion
    rationale: npm publish + OpenAI/Anthropic backends + agent flesh + parallel execution
    confidence: 0.92
  - id: D-049
    decision: Feature milestone — patch tags v0.8.1-v0.8.6 then v0.9.0
    rationale: OpenAI backend, agent flesh, npm publish all feat
    confidence: 0.95
  - id: D-059
    decision: Rename OllamaBaseBackend to LLMBaseBackend + thin OllamaBaseBackend subclass
    rationale: 15 of 17 methods backend-agnostic
    confidence: 0.92
  - id: D-060
    decision: OpenAI/Anthropic backends use native fetch() not SDK packages
    rationale: No dependency bloat; fetch native in Node 18+
    confidence: 0.85
  - id: D-066
    decision: Concurrency limiter internal (no p-limit dependency)
    rationale: 15 lines; avoids dependency for trivial feature
    confidence: 0.90
  - id: D-067
    decision: Promise.allSettled for review agents at orchestrator lines 373-400
    rationale: Current sequential loop replaced with parallel execution
    confidence: 0.88
