/**
* Runnable dual-era stdio MCP server fixture for the dual-era stdio e2e cells.
*
* The connection-pinned `serveStdio` entry over an ordinary `McpServer`
* factory: the client's opening exchange selects the era for the connection
* (a 2025 `initialize` handshake or 2026-07-28 per-request envelope traffic
* negotiated via `server/discover`), and one factory instance serves it.
* Spawned as a real child process (via tsx) by
* test/e2e/scenarios/stdio-dual-era.test.ts; exits when its stdin reaches EOF.
