Copying a file in Finder and pasting it into an SSH pane, or dropping one
onto it, used to paste this machine's path — which the remote program
cannot open. Only clipboard images were uploaded first.
Every local path a pane is handed now goes through one route: uploaded
into its own directory under ~/.cache/tty7/clipboard on an SSH host (so it
keeps its real name), rewritten for WSL, and pasted as-is locally. Folders
upload recursively, a transfer is only abandoned once it stops moving, and
staged pastes older than a week are pruned.
Rows of a remote Files tree now drag as their own type instead of
ExternalPaths, so no drop target mistakes a far-side path for a local file.
