Start an ACP (Agent Client Protocol) server for editor/client integrations

Usage: koda server [OPTIONS]

Options:
      --port <PORT>
          WebSocket port (not yet implemented — use --stdio instead)
          
          [default: 9999]

      --stdio
          Use stdin/stdout JSON-RPC transport (required for VS Code, Zed, etc.)
          
          Reads newline-delimited JSON-RPC 2.0 from stdin and writes to stdout. This is the standard ACP transport for local agent integrations.

  -h, --help
          Print help (see a summary with '-h')
