Subject: [PATCH] fix(deep-link): check update-desktop-database existence
 before executing

On Linux, `update-desktop-database` (from `desktop-file-utils`) may not
be installed, especially on KDE systems. Instead of failing with an IO
error, log a warning when the command is not found and continue.

Non-NotFound errors still propagate as before.

Fixes #2265
