commissioning: the layer, the acceptance tests, the harness rule, the docs, and the bench drills

meta-forgefirm: the forgefirm-users init replays the account at boot;
sshd refuses root and empty passwords and runs only while the panel
turns it on; the release image keeps an empty root password for the
console; the console banner; avahi announces forgefirm.local; https in
libmicrohttpd and ulfius; the panel on 80 and 443; the license bundle on
the rootfs; release.sh checks the root policy on the built rootfs.

forgetest: the commission suites (commission, commission_dark,
commission_sheet: 23 cases); the runner turns cloud mode on with the
typed phrase for a test that declares it; the baseline's motor_lock is
0; the log-export test checks the bundle for the camera key; the record
helpers write bytes as given and join the daemon's paths as POSIX. The
stream harness gains rule 24: a hold verdict is held again after a
resume. Bench drills: lens_travel.py and lens_stop_accel.py.

Docs: BRINGUP carries the present state; CAMPAIGN-LOG carries the dated
record.
