## Summary

Deliver `@suaveplan/api-plugin-game-server` on the genesis branch from scratch at enterprise quality. The package wraps `@suaveplan/game-server`'s `SessionManager` in a Hono HTTP plugin. Routes expose session lifecycle (create, list, join, leave, heartbeat, terminate), player management (add/remove/list), and server health. A `definePlugin()` factory registers the `SessionManager` as an injectable service. Genesis adds Zod request/response schemas, structured errors, OTel route instrumentation, and 100% coverage with Hono test client integration tests.
