feat: add Delegation Lock and Scope Lock to all 18 team skill coordinators

Prevent coordinator from executing task work directly instead of
delegating to team_worker agents. Three-layer enforcement:

- SKILL.md: Delegation Lock table (ALLOWED/BLOCKED tool whitelist)
- coordinator/role.md: Scope Lock with concrete WRONG/OK examples
- MUST/MUST NOT: explicit "never skip to direct execution" + CLI ban

+## Delegation Lock
+
+**Coordinator is a PURE ORCHESTRATOR. It coordinates, it does NOT do.**
+
+Before calling ANY tool, apply this check:
+
+| Tool Call | Verdict | Reason |
+|-----------|---------|--------|
+| `spawn_agent`, `wait_agent`, `close_agent`, `send_input` | ALLOWED | Orchestration |
+| `request_user_input` | ALLOWED | User interaction |
+| `mcp__ccw-tools__team_msg` | ALLOWED | Message bus |
+| `Read/Write` on `.workflow/.team/` files | ALLOWED | Session state |
+| `Read` on `roles/`, `commands/`, `specs/` | ALLOWED | Loading own instructions |
+| `Read/Grep/Glob` on project source code | BLOCKED | Delegate to worker |
+| `Edit` on any file outside `.workflow/` | BLOCKED | Delegate to worker |
+| `Bash("ccw cli ...")` | BLOCKED | Only workers call CLI |
+| `Bash` running build/test/lint commands | BLOCKED | Delegate to worker |
+
+**If a tool call is BLOCKED**: STOP. Create a task, spawn a worker.
+
+**No exceptions for "simple" tasks.** Even a single-file read-and-report MUST go through spawn_agent.
