feat(python): voice-agents v1 — latency-profiling

[github-actions]

Adds the latency-profiling recipe for voice-agents v1 (python).

Measures per-component TTFB across the voice agent pipeline (think/LLM and speak/TTS) by injecting a text message and timestamping each stage event. Prints a latency breakdown per turn.

Closes part of #551
