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

+- Status reports to the user / `request_user_input` prompts

+**Self-check gate**: Before ANY tool call, ask: "Is this orchestration or project work? If project work → STOP → spawn worker."
