The slash guard was the only thing keeping a name out of the directory structure, and nothing tested it: deleting it left the suite green, because creating the launcher directly in the applications directory already makes the redirect fail on its own, with a raw bash error instead of the message. The assertion is on the message now, alongside the traversal case the guard actually closes -- on quattro a name of `../../../../escaped` writes its launcher clean outside the applications directory.
The interactive prompt read the name, fetched the favicon, wrote it and updated the icon cache before the name was ever checked, so a URL typed into the Name field left an icon behind on every attempt. Validating as soon as the name is read covers both paths from one place.
Removing by name also scanned unconditionally, so a machine with no applications directory printed a find error where omarchy-remove-gaming-xbox-cloud does not hide stderr.

The app name becomes a filename, and omarchy-webapp-install ran
`mkdir -p "$(dirname "$DESKTOP_FILE")"` over it, so every slash turned into a
directory level. Typing a URL into the Name field -- the reported way in --
wrote the launcher to
`~/.local/share/applications/http:/127.0.0.1:4000/.desktop`.
Removal could then never reach it. The picker lists the file but displays a
name derived from the path, and the removal rebuilt a flat
`$DESKTOP_DIR/$APP_NAME.desktop` from that name, so `rm -f` deleted nothing and
the app stayed in the launcher with no error.
Refuse a name containing a slash rather than silently renaming what the user
typed, and delete the file the scan actually found instead of a path rebuilt
from its display name. The second half also clears up whatever earlier versions
nested, which a reconstructed path cannot address.
