fix: Projects tab resets focused item on window focus return

[grimmerk]

Problem

When returning to CodeV from background, the Projects tab (react-select) resets the focused/selected item to the first one. Sessions tab preserves position correctly.

Root Cause

onFocusWindow triggers fetchRecentProjectRecord() which calls setPathInfoArray() with a new array reference. react-select treats this as new options and resets focusedOption to the first item.

Sessions tab doesn't have this issue because it uses a custom selectedSessionIndex state that survives data refresh.

Related

Arrow key navigation in Projects tab may also occasionally jump back — likely the same root cause (async data refresh mid-navigation).

Attempted Fixes (didn't work)

• useMemo for pathArray — not enough, upstream setPathInfoArray still creates new reference
• Functional setState with path comparison — didn't take effect (possibly webpack cache, or react-select tracks options by reference internally)

Possible Approaches

1. Skip project refetch on focus if data was loaded recently (TTL check)
2. Track focused option in a ref and restore it after options update (react-select internal API needed)
3. Replace react-select with custom list (like Sessions tab) for full control
4. Debounce/batch state updates to reduce re-renders during focus
