Text paste went through `kitty @ send-text`, which has no bracketed
paste, so multi-line clipboard text ran line by line in a shell. Route
text through `kitty @ action paste_from_clipboard` instead and keep
send-text for the image path only.
Over SSH the typed path pointed at the local /tmp and the remote process
could not read it. Read the focused window's foreground processes from
`kitty @ ls`, and when one of them is an ssh client, scp the image to
that host and type the remote path. Nothing is typed into the focused
app but a path, so this still works when the target is a TUI rather than
a shell. The real ssh process is preferred over the `kitten ssh`
wrapper, whose long options the argument parser does not understand.
Also: mktemp instead of a timestamp that collides within a second,
a prune of clip files older than a day, image/png preferred over
whatever format the source advertises first, and the clipboard tools
pinned so the script does not depend on kitty's inherited PATH.
