Stale task/plan name persists in status bar across restarts

Description

A label ("transform-feature-implementation") has been stuck in the status bar (cyan box, right side, above the input prompt) for over two weeks. It persists across:

• Restarting Claude Code (Ctrl+C + claude)
• Multiple sessions
• Compacting context

The label appears to be a task or plan name from a previous conversation, but it never clears.

Expected Behavior

Status bar labels from previous tasks/plans should not persist indefinitely across new sessions. They should either clear on session start or be tied to active state that the user can manage.

Environment

• Claude Code CLI (terminal)
• macOS
• Model: claude-opus-4-6 (1M context)

Steps to Reproduce

Unable to reproduce on demand — the label appeared during a long session involving plan mode and has been stuck since. No corresponding entry found in ~/.claude/settings.json, settings.local.json, project settings, todos, or git branches.

Screenshot

The cyan box displaying "transform-feature-implementation" appears on the right side of the separator line above the input prompt, and has been there for ~2 weeks across 50+ restarts.
