fix(pi-teamwork): prefer AMaster agent-run auth

[pcdqc]

Summary

• move the AMaster task-tools auth preference from the runtime patch into upstream @amaster.ai/pi-teamwork
• prefer PAPERCLIP_* agent-run auth over session/board/config auth for AMaster Employee CLI calls
• keep amaster-runtime status probes on plain pi.exec and add regression coverage for the auth precedence

Validation

• pnpm --filter @amaster.ai/pi-teamwork test
• pnpm --filter @amaster.ai/pi-teamwork typecheck
• pnpm --filter @amaster.ai/pi-teamwork build
• pnpm exec biome check packages/pi-teamwork/src/index.ts packages/pi-teamwork/src/adapters/amaster.ts packages/pi-teamwork/src/types.ts packages/pi-teamwork/src/tests/index.test.ts
• pnpm typecheck
• pre-commit: pnpm lint && pnpm typecheck && pnpm test && pnpm build

Notes

• Local Node is v22.22.3, so pnpm prints the repo's Node >=24 engine warning locally. Commands above completed with exit 0.
• tests/extension-loading.test.ts still has an unrelated local failure before full workspace build/install: pi-memory cannot resolve @amaster.ai/pi-memory-mem0/dedup and @amaster.ai/pi-storage/json. Full pnpm test passed during the commit hook after workspace artifacts were present.
