feat(highres): add TundraStore/SteriStore plate store driver

[rickwierenga]

Summary

Adds a PyLabRobot driver for the HighRes Biosolutions TundraStore (branded "SteriStore") refrigerated automated plate store. The device exposes a line-based text protocol over TCP port 1000 (ACK! echo → optional data → OK!/ABORTED!/ERROR! completion).

New package pylabrobot/highres/tundrastore/, modeled on the v1b1 Cytomat driver:

• TundraStoreBackend — transport over pylabrobot.io.socket.Socket, with command framing + error-stack parsing. Mixes in the AutomatedRetrieval, TemperatureController, and (read-only) HumidityController capability backends + Driver. Exposes low-level home / pick(stacker, slot, nest) / place / door / barcode commands and status queries (version, doors, nests, spatula, environment, stacker dimensions).
• TundraStoreChatterboxBackend — device-free backend for offline testing.
• TundraStore — Resource + Device frontend (racks → stackers, capability registration), mirroring the Cytomat frontend.
• backend_tests.py — 13 tests driven by real responses captured from hardware (firmware 3.0.0.119, serial HRB-2209-35148), including the real ERROR! home … Unable to close all doors stack.

Validation

• 13 unit tests pass; ruff format/ruff check and mypy clean.
• Verified live against the device (read-only queries): version, homed state, nests, doors, temperature (21.9 °C), humidity, and 14-stacker layout all read back correctly through the backend.

Open question / follow-up

The TundraStore has two transfer nests, but the AutomatedRetrieval capability is single-loading-tray. For now the capability uses a configurable loading_tray_nest (default 1); pick/place can address either nest directly. A proper two-nest mapping is left as a follow-up.

The temperature/humidity setter paths (environmentset TEMP …, environment TEMP off) are constructed from the manual's command grammar but not yet hardware-verified (couldn't safely run state changes during testing). Read paths are verified.

Is this compatible with the AmbiStore? The AmbiStore is the same commands as the TundraStore without the refrigeration.

should be! do you have one to test it with?

[vikichu]

Yes! I will test when I find time! Thanks!

sweet, I dont have one for testing, so would appreciate the feedback there! the docs I have are actually for tundra store but work just the same on steri. look forward to hearing how it goes, please dont hesitate to reach out
