[Recommendation] Replace role-count multipliers with coverage-driven team options

[pate0304]

Outcome

Generate Focused, Recommended, and Extended teams from work-package coverage, risk, verification independence, and coordination cost.

Acceptance criteria

• Focused is a proven minimum cover for required work packages.
• Recommended adds independent verification only for justified risk boundaries.
• Extended adds named lifecycle capabilities without duplicate ownership.
• Zero-evidence filler roles are impossible.
• Conflicts, dependencies, overlap, handoffs, cycles, and fanout are validated.
• Each larger option explains exactly what additional capability it covers.
