## Summary by CodeRabbit

* **New Features**
* Transcriptions now produce structured meeting summaries (strict JSON)
and a normalized, speaker‑tagged, non‑overlapping transcript with legacy
projection support.

* **API**
* Submission accepts richer transcription input; results return
source‑audio metadata, slice manifest, quality indicators, normalized
segments/transcript, and structured summary JSON.

* **Frontend**
* Recording flow stores transcription metadata and uploads preprocessed
audio slices with slice/quality info; UI-side result normalization
applied.

* **Tests**
* Expanded unit, contract, and e2e coverage for normalization, payload
parsing, persistence/retry, and end‑to‑end transcription flows.
