v0.2.37

Fixes the menubar appearing crashed/high-CPU while loading.\n\nRoot cause from live sampling: the app was not generating a new v0.2.36 crash report; it was alive but burning CPU in SwiftUI/AppKit NSImage rendering while the loading overlay's repeatForever animation continuously re-rendered programmatically drawn owl images.\n\nChanges:\n- Removed the indefinite animated loading overlay.\n- Cached the programmatically drawn owl icon as a reusable template NSImage.\n- Verified the local app drops back to 0.0% CPU after launch/refresh and no new crash report appears.
