/**
 * InMemoryEventBus — Synchronous, error-safe event bus implementation.
 *
 * Design decisions:
 * - Synchronous dispatch: correct for Phase 1-2 (single-process MCP server)
 * - Errors in handlers are caught and forwarded to `onError` callback — never break the emitter
 * - Supports wildcard '*' subscriptions
 * - Per-container lifecycle: `removeAllListeners()` for cleanup
