Introduce Valve and Damper as abstract Equip bases for non-actuated equipment. ValveActuator and DamperActuator become intersection types (Actuator & Valve, Actuator & Damper). Adds *thermostatic global marker for feature layering on valves.
7 new Enum types for valve/actuator classification: ValveFunction (11 values), ValveBodyType, ValvePorts, ActuatorFailPosition, ActuatorDirection, ActuatorControlAction, ActuatorMechanism. Adds actuatorDirection slot on Actuator. ValveFunction scoped to piping role — pressureIndependent and thermostatic are feature markers, not function values.

Depends on #53.
7 new Enum types for valve/actuator classification:
ValveFunction— piping role (11 values: isolation, control, balancing, bypass, check, mixing, diverting, pressureReducing, expansion, safety, relief). Scoped to single-select piping role —pressureIndependentandthermostaticare feature markers per Add Valve and Damper abstract base specs #53.ValveBodyType— physical construction (ball, butterfly, gate, globe, needle, plug)ValvePorts— port configuration (twoWay, threeWay, fourWay)ActuatorFailPosition— fail-safe mode (failOpen, failClosed, failInPlace, failToPosition)ActuatorDirection— signal mapping (directActing, reverseActing)ActuatorControlAction— control behavior (modulating, twoPosition, floating)ActuatorMechanism— drive type (electricMotor, pneumatic, hydraulic, solenoid)actuatorDirectionadded as a slot onActuator— it's the one classification that's an active input to control logic and belongs directly on the spec.Files:
