Subject: alacritty-mosh: unique per-launch config paths

The per-target files in /tmp/alacritty were deleted by the session's
cleanup trap, so a second window to the same host (or a relaunch racing
a previous exit) lost its config mid-flight and Alacritty logged
"Unable to load config ... File not found" on live reload. Suffix the
paths with the launcher PID so each instance owns its own files.
