feat: merge 10 team commands into unified team-lifecycle skill

Consolidate coordinate, plan, execute, test, review, spec-coordinate,
spec-analyst, spec-writer, spec-discuss, spec-reviewer into a single
team-lifecycle skill with role-based routing (Pattern B architecture).

- SKILL.md: role router with 8 roles, shared message bus, 3-mode pipeline
- coordinator: unified orchestrator for spec-only/impl-only/full-lifecycle
- 7 worker roles: analyst, writer, discussant, planner, executor, tester, reviewer
- reviewer: dual-prefix (REVIEW-*/QUALITY-*) auto-switching code/spec review
- Each role: 5-phase execution, message bus with CLI fallback, error handling
