Stdio transport writes non-JSON output to stdio

[leovalen]

The README states " Important: When using STDIO transport, never write to STDOUT in your handlers". However the package itself does just this, on line 83-86 in ServeCommand.php, breaking compatibility with Claude Desktop and probably other MCP clients:

$this->info('Starting MCP server');
        $this->line("  - Transport: STDIO");
        $this->line("  - Communication: STDIN/STDOUT");
        $this->line("  - Mode: JSON-RPC over Standard I/O");

These should probably be written to the log instead.

This had already been fixed in #34 and was included in the latest release, v3.1.0. If you update to that version, it should resolve the issue.

Apologies for the inconvenience, and let me know if anything else comes up!
