Summary

Aligns Project Instructions active team governance with the current OWNER-approved active-capable team map.

What changed

• Adds current OWNER clarification that active-capable governance includes Team Alfa, Team Bravo, Team Charlie, Team Delta, Team Gamma, and Team OWNER.
• Keeps Gamma valid and active-capable because another PC may be working on it.
• Adds explicit guidance not to retire Gamma without OWNER approval.
• Preserves historical four-team backlog ownership wording while clarifying it must not exclude Gamma from active-capable governance.
• Updates required Codex report artifacts and creates the local repo-structured ZIP at tmp/PR_26175_OWNER_043-team-registry-gamma-delta-alignment_delta.zip.
