fix(BIZ-42): critical deadlock + major review issues

- Fix #1 (Critical): evaluate_retreat() deadlock — changed _retreat_lock to
  threading.RLock() to allow reentrant acquisition when evaluate_retreat()
  calls get_429_rate() while holding the lock
- Fix #2 (Major): Dashboard queue chart now uses snap.queue.per_priority
  instead of Math.random() mock data
- Fix #3 (Major): structlog uses JSONRenderer instead of ConsoleRenderer
  for JSON-format output as required by acceptance criteria
- Bonus: webui.py _build_snapshot() now async and includes queue data
  with per-priority depth for dashboard consumption

BIZ-42: Phase2 可观测性+WebUI+避退模式 — metrics/health/webui/dashboard/adaptive

新增文件:
- metrics.py: Prometheus 指标端点 (:9191), 10+3 个指标
- health.py: /health (liveness) + /health/ready (readiness)
- webui.py: WebUI 后端 API (SSE 实时推送 + 配置热重载)
- static/dashboard.html: 仪表盘前端 (Chart.js, 令牌桶仪表+队列柱状图+吞吐折线图)

更新文件:
- rate_limiter.py: 增加 AdaptiveTokenBucket 避退模式 (ADR-009)
  状态机 NORMAL→RETREAT→RECOVER, 429 率滑动窗口监控
- server.py: structlog 结构化日志 + 避退反馈回路
  挂载 metrics_server (:9191) + health/ready + webui + /status
- pyproject.toml: 增加 prometheus-client, pydantic, types-PyYAML 依赖

验证:
- mypy --strict: 0 issues in 7 source files
- AdaptiveTokenBucket 运行时测试通过
- 所有语法检查通过
