- Updated EventController to keep foreground render mode active from agent_start through agent_end so live-region rebuild remains enabled during a turn.
- Pinned stop-reason assistant errors to the editor banner and suppressed the transcript's inline Error line while pinned, then restored it on the next agent_start.
- Added tests covering error-banner suppression/restoration and eager native scrollback rebuild ordering before loading animation.
Enable eager native scrollback rebuild mode while assistant text is actively streaming so reflowed Markdown rows do not leave stale duplicated tails in WSL/Windows Terminal scrollback.\n\nFixes #1615
- Added a post-dispatch refresh hook to recompute foreground tool render mode after key turn/tool events.
- Computed whether any non-background pending tool is active and toggled eager native scrollback rebuild accordingly.
- Added a regression test confirming eager rebuild is enabled while foreground tools are pending and disabled when none remain.
