Fault rules for HVAC

FDD fault rule types, YAML format, and expression cookbook for HVAC and building systems. Rules are 100% Brick-model driven: inputs reference Brick classes only; column mapping comes from the Brick TTL and Brick external timeseries references (timeseries storage), which Open-FDD embraces at the heart of FDD.
