ScottW514 b29bb9e023 bench: the controller port and manual home harnesses
Two host harnesses for the grblHAL driver's null-sink build, in the bench
registry and the README with the others. The driver's CI runs them.

ctlport_test.py drives the controller port beside a scripted Grbl sender
that counts every ok and error it is sent, which is the only way to see a
status routed to the wrong source. 13 cases: the socket's mode; a port
jog's status going to the port with the sender's count exact and the jog
run whole under the sender's '?' polls; a port error the sender's next line
does not inherit; the sender's line canceling a fast port jog and drawing
its own ok (fast on purpose: a slow jog stops at once and would pass with no
hold at all); a sender line queued right behind the port's; the refusals;
one client, and five reconnects right after a close; the status hook across
a soft reset; the dead-man; a CR LF sender; a sender that polls the way
LightBurn does, '?' with an end of line behind it, LF and CR LF (every port
jog accepted, a 60 mm port jog run whole with the polls landing inside it,
one ok per poll, a real line still canceling a port jog); and every
operation of both sets under an open armed window with M3 modal and S500,
where the dump must hold no FIRE tick.

manual_home_test.py reads the stream dump (GFSINK_DUMP) and the attribute
log (GFSINK_ATTR_LOG), so it can say that nothing was shipped and which
current was written, and how many times. 9 cases: a manual $H ships no step
and no FIRE tick and declares the offsets with the soft limits on and Z
kept; $H refused in a cycle; $MD refused under an open armed window with
nothing written; every motion source and $X refused while released; each
energize written exactly once; the port's panel operations; both pairs of
home offsets, alone and at once; and a controller killed under a release,
whose replacement writes only 0 and 0.

Both pass against the driver's extensions tree. The poll cases fail against
the driver without its empty-line rule ("8 of 8 port jogs were refused under
a status poll"), which is the defect they were written from: it was found
on the bench reference with LightBurn connected, and the sender these
harnesses had until then polled a bare '?'.

"""The bench diagnostics page: registry of the bench tools and the
subprocess runner behind the #bench tab.
The registry lists every tool of scripts/bench (the README is the human
index; this is the machine one) with its safety class and argument spec.
A tool is runnable from the page once `ported` is set: the script is
installed under the tool directory (/usr/share/forgetest/bench on the
image, override FORGETEST_BENCH_DIR) and runs as a subprocess with the
form's arguments, output streamed to the page. Unported tools are listed
so the catalog of what exists is complete, with Start disabled.
Safety classes:
dry reads or dry motion, no emission, forgectrl stays up
takeover needs forgectrl stopped and the pulse device free
scope a takeover whose result only means something with the named
instrument on the bench (a scope on LASER_PWM / LASER_ON)
live laser emission possible (operator acknowledgment required)
The tools that also run from a LAN host (gfbench.py: GF_HOST) run on the
board here with GF_HOST=127.0.0.1, the panel token in GF_TOKEN, and
their data files under FORGETEST_BENCH_DATA (<data>/bench/). Bench runs
are recorded in <data>/bench.jsonl and never enter a campaign.
