- Extract shared modal-focus-guard module reused by changelog and session-help modals
- Only fold the selected changelog entry on Enter/Space; leave close/refresh buttons and nested folds to their own activation
- Stop re-stealing focus after a mouse click already selected an entry
- Parse prerelease and build metadata separately in version headings (e.g. 0.15.0-rc.1+build.2)
- Resolve tray menu test assertions by label instead of index
