feat: Add 4 new team skills with Generator-Critic loops, shared memory, and dynamic pipelines

Create team-brainstorm (ideator↔challenger GC, quick/deep/full pipelines),
team-testing (generator↔executor GC, L1/L2/L3 test layers),
team-iterdev (developer↔reviewer GC, task-ledger sprint tracking),
and team-uidesign (designer↔reviewer GC, CP-9 dual-track with sync points).
Each team includes SKILL.md router, 5 roles, and team-config.json.
