jensandClaude Sonnet 4.6 96fe7ce90c Require TempController(Smith)'s model params/ambient via setters; add comprehensive process() checks
TempController(Smith).__init__ no longer takes model_params/theta_amb -
set_model_plant_params() and the existing set_ambient_temperature() must be
called instead (mirrors components/plant/pot.py's own Pot constructor
refactor). temp_controller.py's now-pointless model_params/theta_amb
constructor placeholders (kept only for "compatibility" with Smith) are
dropped too.

Both TempController variants now raise a clear RuntimeError from process()
itself if set_params() wasn't called, instead of letting it surface deep
inside Pid.process() as an opaque "'NoneType' object is not subscriptable".
Smith additionally checks its internal models via Pot.is_configured() (new)
and raises if set_model_plant_params()/set_ambient_temperature() weren't
called either.
