Version 0.29.0

Features

lager boxes add now requires --user (breaking change). The implicit lagerdata default has been removed — you must specify the box’s login user explicitly when adding a box.
Read a USB net’s state without changing it. The new lager usb <net> state reports whether a port is on or off, read-only.
Run a one-off command on a Lager Box over SSH. lager ssh --box <box> -- <command> runs a single command on the box and returns its output, like ssh user@host <command>, instead of only opening an interactive shell.
Keithley 2281S battery-simulator internal resistance. You can now set the simulated ESR in battery-sim mode (:BATT:SIM:RES:OFFSet).
Keithley 2281S two-quadrant current readback. Charger and sink testing now reads back negative (sink) current correctly instead of reporting 0.

Multi-hub Acroname boxes address the right hub. A Lager Box with more than one Acroname USB hub now binds each USB net to its own hub by serial number, so commands no longer land on the wrong hub.
YKUSH USB hubs recover automatically. A stale or transient YKUSH handle is now auto-recovered, and the hardware service self-restarts after a power-cycle instead of staying wedged.
The Keithley battery/supply monitor self-heals after a power-cycle. A non-intrusive liveness probe detects a dropped VISA session and restarts the hardware service automatically, so the supply/battery TUI keeps working without manual intervention.
A wedged USB hub no longer takes down USB control. box_http_server now self-restarts to recover a wedged hub.

lager usb <net> toggle reports the resulting state. Toggling a port now tells you whether it ended up on or off.
Documentation refresh. Added a devenv reference page and a J-Link section to lager diagnose, documented the DP711 crossover-cable requirement, refreshed the debug/boxes docs, and removed dead pages.
