- Fix spurious SyncUp every few seconds when Git LFS left a stale
.git/lfs/is_behind marker; run SyncDown when LFS catch-up is needed
- Run git lfs pull only when the remote has new commits or the marker
exists, not on every poll
- About dialog: check markusstoll/SparkleShare GitHub releases/latest
for updates instead of sparkleshare.org
- After wake from sleep, run sync on a background thread (avoids UI freeze)
- About: single-line update hint with clickable “(download)” link;
shorter credits text; layout fixes for original window size
- About shows CFBundleShortVersionString from the app bundle (matches
Finder / Get Info)
- Release builds: dotnet clean per architecture in release-mac-dmgs.sh;
Release rebuild in build-mac.sh to avoid stale MonoBundle DLLs
