v1.0: cc_parallel.py — parallel CC workers with git worktree isolation

- Up to 5 CC workers run concurrently
- Each worker gets its own git worktree (no file conflicts)
- Auto-merge branches when all workers succeed
- --merge auto|always|none control merge strategy
- --json output for Hermes integration
- Tested: 2 workers, 21s total (vs 47s sequential)

+Claude Code Parallel Orchestrator v1.0
+并行运行多个 CC 子 agent，每个在独立的 git worktree 中工作。
+
+架构：
+  Hermes (协调器)
+    ├─ CC Worker 1 → worktree-1 (branch: parallel/task-1)
+    ├─ CC Worker 2 → worktree-2 (branch: parallel/task-2)
+    └─ CC Worker N → worktree-N (branch: parallel/task-N)
+
+用法：
+  # 双任务并行
+  python3 cc_parallel.py \\
+    --task "Implement CharacterModel.ts" \\
+    --task "Implement CharacterView.tsx" \\
+    --cwd ~/projects/oes-web2 --max-turns 8 --timeout 300
+
+  # 三任务 + 自定义 worktree 前缀
+  python3 cc_parallel.py \\
+    --task "Task A" --task "Task B" --task "Task C" \\
+    --cwd ~/project --prefix feat
+
+  # 合并模式（默认 auto = 全部成功才合并）
+  python3 cc_parallel.py \\
+    --task "A" --task "B" \\
+    --cwd ~/project --merge auto
+
+隔离原理：
+  git worktree add ../project-worker-1 -b parallel/task-1
+  每个 CC 在自己的 worktree 中工作，互不干扰。
+  完成后 git merge 将各分支合回主分支。
