/**
 * Express HTTP Manager
 *
 * Manages HTTP server lifecycle for Streamable HTTP transport.
 *
 * Serving is stateless per protocol revision 2026-07-28: there are no
 * protocol-level sessions and no `Mcp-Session-Id` header. Every request is
 * answered by a fresh server instance from the factory via the SDK's
 * `createMcpHandler` entry, which speaks the 2026-07-28 revision and falls
 * back to stateless serving for 2025-era clients on the same endpoint.
 *
 * Key Features:
 * - /mcp endpoint → per-request stateless serving for both protocol eras
 * - /health endpoint → liveness check
 * - DNS rebinding protection → Host/Origin validation from the SDK Express app
 * - Graceful shutdown → closes open subscription streams, then the HTTP server
 *
 * @example
 * ```typescript
 * const manager = new ExpressHttpManager(
 *   config,
 *   () => TouchDesignerServer.create(), // Server factory
 *   logger
 * );
 *
 * // Start server
 * const result = await manager.start();
 *
 * // Graceful shutdown
 * await manager.stop();
 * ```
