- Removed terminal risk mode toggles from config, terminal state collection, and render controllers.
- Dropped snapshot freezing, thaw tracking, and finalized-block replay in transcript rendering.
- Removed clear-on-shrink settings and initialization hooks from selector and interactive mode flows.
- Simplified render scheduling by using requestRender() without mutation flags or stream checkpoints.
- Added a sealed state to `ReadToolGroupComponent` to force-close a read group when a turn ends without a read result.
- Updated transcript finalization to treat pending read entries as active unless the group is sealed, preventing premature finalization when outputs are still in flight.
- Expanded turn-end pending-tool cleanup to seal `ReadToolGroupComponent` instances in addition to `ToolExecutionComponent`.
