Desktop entry + foot-style positional command

cce-terminal.desktop (Categories=System;TerminalEmulator;) makes the
app visible to the launcher's Apps grid and the settings Default Apps
Terminal row, per the in-crate entry convention. Icon=cce-terminal per
convention — the cce-icons artwork does not exist yet.

Bare trailing args now run as the command (foot-style), alongside the
existing xterm-style -e: the launcher hosts Terminal=true entries
positionally (`term sh -c …`), so being pickable as the default
terminal requires accepting that convention.
