docs: update README roles from codenames to current descriptions

Replace Final Fantasy-inspired role codenames with generic descriptions:
- Strago (Build spec author) → Build Spec: Architecture and specification
- Cid (Implementation, benchmarks, deployment) → Implementation: Code, benchmarks, deployment
- Locke (Research support, upstream watch) → Research: Upstream tracking, literature review
- John (Quality review) → Quality: Testing and review
- Frankie (Coordination) → Coordination: Project management

Note: Forge URL (143.198.27.163:3000) already updated in main via PR #148 (closes #46).
