feat: apply Pattern 10 to all team skills — @ strong refs + workspace resolution

- SKILL.md: coordinator entry uses `@roles/coordinator/role.md` strong reference
- coordinator/role.md: command delegations use `@commands/xxx.md` prefix
- coordinator Phase 2: resolve project_root + skill_root via `Bash pwd` before TeamCreate
- Worker Spawn Template: role_spec uses absolute path from session skill_root
- skills_lib/team-skill-designer: document Pattern 10 + add quality checks

Covers 17 team skills: team-lifecycle-v4, team-frontend, team-ultra-analyze,
team-ux-improve, team-arch-opt, team-brainstorm, team-review, team-uidesign,
team-issue, team-iterdev, team-perf-opt, team-planex, team-quality-assurance,
team-testing, team-tech-debt, team-coordinate, team-roadmap-dev, team-frontend-debug

 ### Initial Spawn
 
 Find first unblocked tasks and spawn their workers. Use SKILL.md Worker Spawn Template with:
-- `role_spec: ~  or <project>/.claude/skills/team-ultra-analyze/roles/<role>/role.md`
+- `role_spec: <skill_root>/roles/<role>/role.md`
 - `team_name: ultra-analyze`
