fix: address cross-vendor review feedback

- Fix focus: use autoFocus on CommandInput instead of e.preventDefault()
- Fix filter: prioritize city segment match (return 2 for slash match)
- Fix handleSelect: always select, don't toggle-deselect
- Add aria-haspopup to trigger button
- Use defensive placeholder logic
