Add disable telemetry configuration as a flag to codegraph serve

[juancarlosjr97]

Hello,

As part of our internal codegraph we have been doing a environmental variable to disable telemetry, but it would be great it this could be part of a flag such as --no-telemetry

{
  "mcpServers": {
    "codegraph": {
      "command": "codegraph",
      "args": [
        "serve",
        "--mcp",
        "--no-telemetry"
      ]
    }
  }
}

This would be making easier to share too

Thank you!
