Summary

• Extracts thread status indicator logic from Sidebar into reusable ThreadStatusIndicators component
• Adds ThreadRowLeadingStatus and ThreadRowTrailingStatus components to display PR state, terminal status, and environment labels in the command palette
• Refactors buildThreadActionItems to support custom leading/trailing content renderers for flexibility across different UI contexts
• Updates CommandPaletteResults layout to properly render inline status indicators alongside thread titles
• Maintains parity with sidebar status indicators (PR open/closed/merged, terminal running, remote environment cloud icon)

Testing

• Verify thread status dots and PR indicators appear in command palette search results
• Confirm PR status tooltips display correctly (# PR open: title format)
• Check that remote environment label displays with cloud icon when thread is on non-primary environment
• Verify terminal-running indicator pulses when background terminal process is active
• Confirm status indicators are accessible (aria-labels, sr-only labels for compact mode)
• Check that all existing sidebar thread status functionality remains unchanged
