Create Daily.co rooms and start a cloud recording via the REST API

Steps

1. Obtain a Daily API key from your Daily dashboard; all REST API requests require an Authorization header with your API key.
2. Create a room by sending a POST request to https://api.daily.co/v1/rooms with a JSON body specifying name, privacy ('public' or 'private'), and properties such as enable_recording: 'cloud' to allow cloud recording in that room.
3. Generate a meeting token for a participant by POSTing to https://api.daily.co/v1/meeting-tokens with room_name, start_time (Unix timestamp), exp (expiry), and is_owner: true for hosts who can manage the recording.
4. From an owner participant in the room, call callObject.startRecording() in the daily-js client SDK (or trigger via the REST API) to start a cloud recording; the recording captures a composite of all participants.
5. Monitor recording status via the 'recording-started' and 'recording-stopped' events on the callObject, or by polling GET https://api.daily.co/v1/recordings which lists completed recordings with download links.
6. To include a transcript alongside the recording, pass dataOutputs: ['transcript-webvtt'] in the startRecording() options; Daily generates a WebVTT file downloadable alongside the MP4 recording.
