fix(terminal): name this app's CLI launcher by absolute path in every local terminal

ORCA_CLI_COMMAND meant three things by lane: an absolute launcher for a structured session, a bare
name for WSL, and nothing for any other terminal, so a structured session's terminal view lost it.
Local terminals now get the same absolute launcher the structured lane gets; WSL keeps its guest
command name, and a terminal whose launcher does not resolve still gets none.
