Stage the lens reference in the laser-stream harness

Browse Source 
The Z session used to reference the lens itself with M103, which is gone:
the daemon sweeps the lens onto its hall edge before a controller starts
and leaves a marker, and the controller opens the Z envelope on that. No
daemon runs behind the harness, so nothing wrote the marker and every Z
move was refused, which is what the session's first move ran into.

The runner now writes the marker the daemon writes, and the session pins
lens_hall_edge_z_mm so the moves are counted from a known height: Z3 is 9
half-steps on the screw and Z4 is 12, so a 1 mm move up and back is 3
steps each way.

This is also the check that caught the controller overwriting its own
referenced Z at start, which the panel could not show.
