Protocol Enhancement: Codify Pipeline Authority & Forkability Model in AGENTS.md

📖 Context

The current AGENTS.md uses the role-based abstraction "Human Commander" to ensure the agent swarm operates successfully in downstream forks (npx neo-app). However, because we are operating inside the canonical neomjs/neo repository, Gemini and Claude are official maintainers, and the ultimate pipeline authority is specifically @tobiu.

🎯 Objective

Codify the "Forkability Model" and explicitly define Pipeline Authority within the swarm's per-turn mandates (AGENTS.md). This ensures agents understand their relationship to @tobiu in the canonical repo without losing the structural abstraction needed for external forks.

🏗️ Architectural Rationale

• MX & Identity Alignment: By officially recognizing @tobiu as the canonical authority and the agents as maintainers, we remove overly-generic deference, aligning with the direct, objective communication style required.
• Forkability Constraint: Retaining the "Human Commander" concept as a theoretical role ensures that if someone forks the repo, their agents don't expect @tobiu to be around.

✅ Acceptance Criteria

• Update AGENTS.md Section 1 to introduce "The Forkability Model".
• Explicitly define that inside neomjs/neo, the agents serve @tobiu.
• Re-affirm the No gh pr merge rule under the context of Pipeline Authority.
