Fixed
Watched folders now survive relaunch under the App Sandbox.
Previously only the folder path was persisted, but macOS revokes a sandboxed app's folder access between launches. After a reboot the app could no longer read the folder, so every scan, live-watch, and rescan silently returned nothing (while free space still displayed — making it look "loaded"). Folders are now persisted as security-scoped bookmarks, and access is re-asserted via startAccessingSecurityScopedResource() before any filesystem read.
Note: Folders added under an older path-only build (e.g. 1.8.3) must be removed and re-added once so a bookmark gets minted.
