v0.12.0: watch run 并行化 + portfolio summary + CI/release 自动化

#54 watch_run 并行化：
- 重构 watch_run 为 multiprocessing.Pool（默认 workers=4）
- 49 只串行 60-90min → 并行 ~15-20min (4x 加速)
- 新增 --workers N（默认 4）和 --serial（强制串行，调试用）
- 单股逻辑提取为 _run_single_subprocess (可独立调用)
- imap_unordered 边跑边汇总评级变化

#55 CI + 自动 release：
- .github/workflows/ci.yml：PR + push 时 Python 3.10/3.11/3.12 跑 pytest + CLI 冒烟
- .github/workflows/release.yml：v*.*.* tag 触发自动 release
  + 跑测试 + 自动生成 changelog（since last tag）+ GitHub Release

#56 portfolio summary（依赖 #47 买入价）：
- 新 stockwise portfolio summary 命令
- 总成本/总市值/总浮盈 + 加权 5y ROE/PE/股息率
- 行业集中度（>30% 标红集中风险）
- 卖出信号热力（high/medium 计数）
- 评级分布 + 单股浮盈明细（按浮盈率降序，超 5% 标色）

测试：76/76 pass。
