THEN Configure the filesystem server to use MCP Roots (recommended) instead of command-line arguments. The client sends roots on initialization and can update them via notifications/roots/list_changed. This allows runtime directory changes. Ensure the server is not started without roots or command-line directories, otherwise initialization fails.

// In client: send initialize with capabilities.roots: true
// After connection, server requests roots/list, client returns roots array.
// To update, client sends notifications/roots/list_changed, server fetches new roots.
