install @ai-agent-ledger/mcp-gateway on VS Code

Requires Node 18+ on your system so npx can fetch the package on first run. VS Code (Copilot) uses a `servers` root key with an explicit `type` field — different from the `mcpServers` shape used by Claude Desktop and Cursor. Paste the config below, then follow the reload step to register @ai-agent-ledger/mcp-gateway.

{
  "servers": {
    "filesystem": {
      "type": "stdio",
      "command": "npx",
      "args": [
        "-y",
        "@modelcontextprotocol/server-filesystem",
        "C:/work"
      ]
    }
  }
}
