## Why
Loaded transcripts reduce several tool calls and file changes to basic status summaries, losing details available in live history cells.
## What changed
- Reuse rich history cells for completed commands, MCP calls, patches, agent activity, image generation, and notices.
- Add dynamic tool cells with bounded output previews while retaining arguments and full output in detailed and raw views.
- Preserve last-known statuses for incomplete calls, unavailable results, and declined or failed operations. Keep legacy command text and terminal interaction output when rich reconstruction is unavailable.
- Remove redundant move annotations from patch diffs and retain patch activity IDs.
- Filter untrusted control characters before emitting terminal scrollback, while preserving semantic hyperlinks.
## Testing
Add unit and snapshot coverage for compact and detailed tool rendering, status fallbacks, retained output, patch restoration, and control-character filtering with and without hyperlinks.
