## Why
The TUI ignored dynamic tool items, and replayed tool activity could differ from live output. Concurrent tool completion also needs to preserve transcript order when writing to terminal scrollback.
## What changed
- Retain dynamic tool rows, update them when calls finish out of order, and mark unfinished calls interrupted when a turn ends.
- Queue terminal output behind unfinished dynamic tools and drain settled rows in bounded batches. Preserve queued output through stream consolidation, resize, and rollback without emitting it twice.
- Align replayed file changes, MCP results, and exploration groups with live rendering. Keep hidden reasoning and terminal interaction details within compatible activity groups, and preserve finalized plan fragments.
- Ignore stale history-page responses, bound turn metadata requests to missing turns, and insert older history after session headers. Keep hidden review prompts as activity-group boundaries.
## Testing
Add regression tests and snapshots for out-of-order tool completion, interruption, ordered scrollback emission, rollback, deferred usage updates, replay consistency, overlapping history, and repeated hidden prompts.
