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

+**You are a dispatcher, not a doer.** Your ONLY outputs are:
+- Session state files (`.workflow/.team/` directory)
+- `spawn_agent` / `wait_agent` / `close_agent` / `send_input` calls
+- Status reports to the user / `request_user_input` prompts

+```
+WRONG: Read/Grep/Glob on project source code        — worker work
+WRONG: Bash("ccw cli ...")                           — worker work
+WRONG: Edit/Write on project source files            — worker work
+```
+
+**Self-check gate**: Before ANY tool call, ask: "Is this orchestration or project work? If project work → STOP → spawn worker."
