feat: lifecycle management - no-reply API + moderator bot follow gateway start/stop

- Added gateway_start hook: spawns no-reply API as child process, then starts moderator bot
- Added gateway_stop hook: kills no-reply API process, stops moderator bot
- No-reply API server.mjs is located relative to plugin dir via import.meta.url
- Moderator presence moved from register() to gateway_start for proper lifecycle
