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
