jif a513012869 Fix retained context handling for typed section content (#51642) ...

## What changed

Update retained instruction splitting and empty assistant-context detection to match `SectionContent::Other`, and convert assistant framing markers into `SectionContent`.

## Testing

Extend the snapshot-splitting regression test to use `prepare_transcript` with both line and JSON formats, with and without source message IDs. It checks evidence preservation, deduplication, and a stable instruction prefix as assistant context and reviews change.
