Conversation
Introduce Prometheus metrics for TTS latency and record them in the TTS code paths. Adds a new src/prometheus/__init__.py exporting a Histogram (om1_tts_latency) and Gauge (om1_tts_latency_last), instruments both audio_output_stream.py and audio_output_live_stream.py to measure request duration and update the metrics, and adds prometheus-client to pyproject.toml (lockfile updated). This provides visibility into TTS processing latency for monitoring.
Regenerated Poetry lockfile, updating the content-hash. No other dependency or source changes were made; this reflects a lockfile refresh (e.g., after running `poetry lock`).
Add urllib3 2.7.0 to pyproject.toml and update poetry.lock to reflect the upgrade. The lockfile bumps urllib3 from 2.6.3 to 2.7.0, updates its python-versions requirement to >=3.10, and refreshes package file hashes and the lockfile content-hash.
