Add multi-agent collaboration system with 16-person team and two-tier governance

- agents/README.md documents company principles (first principles + practical
  delivery), 6-stage collaboration flow, and two-tier governance: CEO has
  highest priority and final say; work groups self-govern internally for
  staffing, scheduling, technical choices within CEO-defined boundaries.
- 16 employees recruited to match CPU physical core count, enabling up to
  16 subagents to run in parallel. Each profile.md has independent name,
  background, strengths, weaknesses, and performance log.
- Roles: 1 CEO, 3 architects (lin/yang/huang), 5 engineers (zhao/chen/li/
  zhou/sun), 3 QA (wang/liu/xu), 2 DevOps (ma/hu), 1 designer (zhu),
  1 writer (deng), 1 security (cao).
- Five working groups defined under agents/groups/: grp-quality-core,
  grp-ai-plugins, grp-cli-ux (B3), grp-build-matrix, grp-security-audit.
