Version 0.28.1

Features

spi, i2c, and energy-analyzer instruments now run on the Lager Box’s warm path. These roles previously went through the box’s per-command Python executor; they now run in the long-lived box server alongside gpio/adc/dac/eload/thermocouple/watt-meter, removing an interpreter spawn and device re-open on every command. Behavior and dashboard logs are unchanged, and energy-analyzer read durations are clamped to 0.1–30s. The rollout is back-compatible — an older Lager Box automatically falls back to the previous path.
WebSocket transport support added to the Lager Box. The box image now bundles simple-websocket, so clients can use a native WebSocket connection instead of long-polling, negotiated automatically.

lager ssh now uses the key set up by lager authorize. Authorized Lager Boxes were still dropping to a password prompt because lager ssh didn’t offer ~/.ssh/lager_box; it now does when that key exists, while leaving the password fallback intact for boxes that haven’t been authorized.
UART devices are now opened exclusively. A second user of a serial port — another dashboard session, or lager uart while a Workbench session is live — now fails fast with a clear “device in use” message instead of silently interleaving reads on the same port.
