close server in stdio is not work as expected

[vincent-pli]

I try to test with external server like shit:

    "sqlite": {
      "command": "uvx",
      "args": [
        "mcp-server-sqlite",
        "--db-path",
        "/tmp/foo.db"
      ]
    },

It's a stdio one, but I cannot close it by client.Close()(

mcp-go/client/stdio.go

Line 93 in a0e968a

func (c *StdioMCPClient) Close() error {

), it's sticked, seems uvx not respect the cmd.wait()
