VibeLign v2.1.9 Release Notes

VibeLign v2.1.9 is a GUI quality-of-life release focused on faster BACKUPS tab loading and clearer restore preview presentation.

What changed

BACKUPS tab now renders instantly on revisit. The last loaded backup list is cached in memory and used as the initial render seed; fresh data is fetched in the background on every visit (stale-while-revalidate).
BACKUPS data is prefetched in the background as soon as a project is opened, so the very first BACKUPS click after entering a project no longer pays subprocess cold-start latency.
Restore preview card now shows visual chips for time, file count, and safety state (relative time + file-count badge + safety check) instead of a plain text line.
Added formatRelativeTime helper for human-friendly elapsed time labels (방금 / N분 전 / N시간 전 / N일 전, with absolute fallback after 7 days).

All changes live in the React/TypeScript layer; no native-side or platform-specific code was touched.
The underlying vib sidecar bridge was unchanged, so Windows and macOS share identical behavior.
Memory cache is process-scoped and keyed by project directory, so switching projects does not leak data between caches and a restart starts cleanly.

TypeScript type-check passed locally.
BACKUPS tab manually verified: instant render on revisit, save/restore flow refreshes the list correctly.
