Detect AppImages that crash immediately after spawning (within 1.5s) by
capturing stderr and using try_wait(). Show a full AlertDialog with a
plain-text explanation, scrollable error output, and a copy-to-clipboard
button. Covers Qt plugin errors, missing libraries, segfaults, permission
issues, and display connection failures.
Move launch operations to background threads in both the detail view and
context menu to avoid blocking the UI during the 1.5s crash detection
window.
Suppress all 57 compiler warnings across future-use modules (backup,
notification, report, watcher) and individual unused fields/variants in
other core modules.
- fuse.rs: Replace Command::new(appimage_path) with 256KB binary scan for
runtime detection - prevents apps like Affinity from launching on tile click
- fuse.rs: Read only 12 bytes for Type 2 magic check instead of entire file
- security.rs: Use find_squashfs_offset_for() instead of executing AppImages
with --appimage-offset flag
- updater.rs: Read only first 1MB for update info instead of entire file
- detail_view.rs: Click screenshots to open in lightbox dialog
- detail_view.rs: Fetch favicons from Google favicon service for link rows
