Description (problem / solution / changelog)

Problem

Fixes #63189

The TUI streaming status indicator (⠼ streaming • xxxm xxs | connected) gets stuck forever after a response completes. The timer keeps counting indefinitely and the only workaround is Ctrl+C or sending another message.

Root Cause

In tui-event-handlers.ts, both finalizeRun() and terminateRun() only call setActivityStatus() when wasActiveRun is true. If the chat:final event arrives after activeChatRunId has already been cleared (e.g., by a lifecycle:end agent event or a concurrent run), wasActiveRun evaluates to false and the status remains stuck at "streaming".

Fix

Two-pronged approach for robustness:

1. Safety-net in finalizeRun / terminateRun (event-handlers)

When wasActiveRun is false but no active or pending session runs remain (activeChatRunId === null && sessionRuns.size === 0), unconditionally reset the activity status. This handles the race condition between lifecycle and chat events.

2. Streaming idle timeout (tui.ts)

Arms a 30-second safety timer whenever the TUI enters streaming or running state. Each incoming delta resets the timer. If no status update arrives within the window, the UI auto-resets to idle. This acts as a last-resort fallback for any scenario where the final event is lost entirely (e.g., WebSocket reconnect gap).

The timeout only applies to streaming and running states — sending and waiting are excluded since those pre-response phases can legitimately take longer.

Testing

• All 22 existing TUI event handler tests pass ✅
• Added 1 new test covering the runId-mismatch scenario (23 total) ✅

Changes

• src/tui/tui-event-handlers.ts — safety-net idle reset in finalizeRun and terminateRun
• src/tui/tui.ts — streaming idle timeout (30s) in setActivityStatus
• src/tui/tui-event-handlers.test.ts — regression test for #63189
