feat(python): speech-to-text v1 — stt-ai-tts-pipeline

[github-actions]

Adds the stt-ai-tts-pipeline recipe for speech-to-text v1 (python).

This is a user-requested end-to-end pipeline recipe demonstrating:

1. STT — transcribe audio with Nova-3
2. Audio Intelligence — sentiment analysis, topic detection, and summarization
3. TTS — speak the generated summary aloud with Aura-2

All three Deepgram capabilities in a single Python script, no third-party services required.

Closes #501
