Function: openPackedMcpServer()
openPackedMcpServer(
options):Promise<PackedMcpSession>
Spawns a built stdio MCP entry and connects a real MCP client to it.
The entry must already exist: build the artifact once per suite and reuse the session for every assertion. A connect failure reports the captured stderr, because a generated entry that dies on startup says why there and nowhere else.

Returns
Promise<PackedMcpSession>
