etwenandClaude Opus 5 c3b0d49145 fix(session): Clear the last run's jobs and session before starting

After a run that ended badly - Tera Term closed, DUT rebooted mid-soak,
macro stopped by hand - the stress jobs kept running and the test session
stayed open. The next run then started on a box that was already loaded.
Nothing errored; the numbers were just quietly wrong.

Script A now opens with hw-test-session finish, bgctl reset --yes,
bgctl stop --all, then bgctl list. The list is the point of the sequence:
it is the one line in the log that proves the DUT was idle at the start.

Script A -> V1.1.1.

v1.1.1 — A run no longer inherits the last one's leftovers

🐛 Bug fixes

A previous run's jobs and session survived into the next one

Script A now clears the box before it starts: hw-test-session finish, bgctl reset --yes, bgctl stop --all, then bgctl list so you can see it came back empty.
This matters after a run that ended badly — a closed Tera Term window, a DUT reboot mid-soak, a macro stopped by hand. The stress jobs kept running and the session stayed open, so the next run started on a box that was already loaded. Nothing failed; the numbers were just quietly wrong, and the only hint was a bgctl list nobody was reading.
The bgctl list at the end is the point of the sequence, not decoration: it is the one line in the log that proves the DUT was idle when the run began.

File	Contents
`Script_ABC_Blanton_V1.1.1.zip`	The full Tera Term working directory, including `Blanton_Script/` to copy onto the DUT

After copying to the DUT:

chmod +x ~/Blanton_Script/*.sh      # see below
grep -rlU $'\r' ~/Blanton_Script    # expect no output

blanton_ber.sh is invoked by Script C as ./Blanton_Script/blanton_ber.sh, so it needs the execute bit along with bmc_monitor.sh and usb_target.sh — and neither git nor a Windows/USB copy carries it reliably. Without the chmod the BER section fails with Permission denied and the log simply has no BER in it.

⚠️ Before you run

hw-test-session finish at the start will complain if no session is open. That is expected on a fresh DUT and does not stop the run.
These three tests cannot share the switch. blanton_ber.sh, blanton_tr518.sh and blanton_traffic_linespeed all take over port loopback and L2 learning. Script C already orders BER after the traffic report.
PRBS takes the links down while blanton_ber.sh is armed. That is the test working, not a fault.
ce0 keeps running until you stop it. If a run is interrupted between start and stop, the 100G port stays saturated with nothing in show interfaces status to hint at it.
Two numbers must stay in step: Script C's sleep 30 and blanton_ber.sh's BER_INTERVAL.
FAN_SPEED is 100 — the fans run flat out unless you change config.ttl.
Declare the switch population with SWB_UNIT0 / SWB_UNIT1.
PRBS on the two 100G uplinks (port_prbs_monitor.sh) is still not wired into the macros.
The three items listed as unverified in v1.1.0 are still unverified: the ce0 ingress mirror, the 120s settle in blanton_tr518.sh, and test mode nr=no on stop. See v1.1.0 for the one-command check on each.
