Format of the transcript_json payload. Tells Cekura how to parse roles and timestamps.

• vapi — Vapi webhook format: [{"role": "bot"|"user", "message": "...", "time": 0.0}]
• retell — Retell webhook format
• elevenlabs — ElevenLabs format
• livekit — LiveKit format
• pipecat — Pipecat format
• deepgram — Deepgram format
• cekura (default) — [{"role": "Testing Agent"|"Main Agent", "content": "...", "start_time": 0.0, "end_time": 2.5}]. Valid roles are "Testing Agent" and "Main Agent" only — using "agent" or "user" will return a validation error.
• none-mono — mono audio with no transcript; Cekura generates the transcript automatically.
