Agent Manager Scope

This repository only owns Heicode sub-mode runtime behavior.

Rules for all files under this repository:

Do not add or restore standalone swarm-mode product features.
Treat /api/swarms as a sub-mode compatibility API, not a generic swarm product API.
Do not add /api/swarm/* endpoints, swarm-only docs, or swarm-only tests.
When refactoring, prefer names and comments that reflect sub-mode runtime ownership.
If a feature belongs to the separate swarm system, remove or reject it here instead of integrating it.
