The committed docs still described the 2026-06-04 presence-aware daemon. Bring
them in line with what is actually deployed: HA computes the setpoint, the host
is a thin actuator (COMMAND_ENTITY/STALE_SECS/HA_GRACE_SECS), additive bias,
anti-flap hold-last, and the new HA readout sensors (command/equilibrium/
cpu_load/fan_speed_avg/fan_power_avg). Earlier doc edits were made in a clone
lost in the workstation reshuffle; re-created here.
