"""sanad_api_go2 — Go2 fleet TELEMETRY agent.
Pushes the Unitree **Go2**'s live status to the YS Lootah fleet server:
POST {SERVER_URL}/api/v1/fleet/ingest/telemetry (Bearer device token)
body: { "sn", "mac", "battery", "charging", "status", "position":{x,y}, "faults":[] }
Same shape/cadence as the R1 agent. The DIFFERENCE is the DDS family:
* Go2 uses **unitree_go** (not unitree_hg).
* Go2 battery lives INSIDE LowState_ as a nested ``bms_state`` (soc/current) —
there is NO separate rt/lf/bmsstate topic like the G1/R1. So this agent reads
battery straight from rt/lowstate.bms_state.
* position (optional) from SportModeState (rt/lf/sportmodestate) or rosbridge /odom.
⚠️ UNVERIFIED ON HARDWARE: written from the unitree_go SDK layout but not yet run
on a real Go2. Confirm the bms current sign (charging) and sportmodestate fields
on the robot. Degrades to heartbeats if unitree_sdk2py is unavailable; --simulate
tests the upload path without a robot. SAFETY: never commands motion (read-only).
