Greptile Summary

This PR improves the findClaudePane function in internal/daemon/monitor.go to prioritize the active pane when detecting Claude sessions. The change implements a two-pass search strategy: first checking if the currently active pane contains a Claude session, and only searching through all panes if the active one doesn't match.

Key changes:

• Added first pass that checks only the active pane for Claude session
• Existing logic moved to second pass as fallback
• Ensures the most relevant (active) pane is detected first, improving user experience when multiple panes exist

Confidence Score: 5/5

• This PR is safe to merge with minimal risk
• The change is a straightforward optimization that adds a prioritization step before the existing fallback logic. The original logic is preserved as a second pass, ensuring backward compatibility. The implementation follows Go best practices and matches the existing code style.
• No files require special attention
