/**
 * Authentication provider that uses the OAuth 2.0 device code flow.
 *
 * When an access token cannot be acquired silently, the provider calls
 * `acquireTokenByDeviceCode` and invokes `deviceCodeCallback` with the
 * response containing `userCode`, `verificationUri`, and `message`.
 * The user opens the URL on any device, enters the code, and authenticates.
 * No local HTTP server is required, making this the recommended mode for CLI tools.
 *
 * @example
 * ```ts
 * const provider = new AuthProviderDeviceCode(msalClient, {
 *   deviceCodeCallback: (response) => console.log(response.message),
 * });
 * ```
 *
 * @see AuthProviderInteractive - Browser-based login with a local callback server.
 * @see AuthProvider - Silent-only provider (base class).
