olliem-oai a0b85c7a66 Fix Guardian retained context spacing and empty assistant handling (#48158) ...

## Why

Complete assistant messages with empty text can produce misleading omitted-context notices in Guardian reviews.

## What changed

- Skip complete, empty assistant messages when recording and rendering retained context, while preserving omission notices for incomplete messages.
- Separate retained instruction fragments with blank lines and keep blank lines free of role prefixes, while labeling every nonempty line with its original role.
- Update source-order guidance detection and empty-section deduplication for the added spacing.

## Testing

Extend retained-context tests to cover empty completed messages across resume, restored empty messages, incomplete-message notices, blank-line spacing, and role labeling. Update Guardian prompt snapshots.
