The argv click command closed injection through the hint's value, but the
sender still handed the headline and description to notify-send bare. A
value beginning with a dash is parsed there as flags, and one shaped like
`--hint=string:omarchy-exec-argv:[...]` is read as a hint of its own --
libnotify keys hints in a hash table, so the later of two replaces the
earlier and a forged headline outranks the vector --exec built.
That is reachable without any --exec in sight: omarchy-tailscale-send
passes a single file's basename verbatim as the description, so a file
named like the hint gives its click action to whoever chose the name.
Put the headline and description behind a `--` so notify-send reads them
as text, and refuse any pass-through word carrying omarchy-exec-argv --
--exec is the only thing that may build a click command.
