config.json.templ's component names already default to "sim" for every backend (sensor/heater/stirrer/plant), making the separate .sim template mostly redundant - it only differed in dt/sim_warp_factor/PID gain tuning, which .templ now adopts directly. Removes config.json.sim, updates brewpi.py's CLI args (-m/--logdir replaces the unused -d/--model/--sim flags), and refreshes the README/TODO references that pointed at the now- removed file.
