ChemicalReactor Abstract Device subclass representing a catalytic reactor vessel.

Reactor is more specific than the general Device (AgenticEntity): it restricts
carried_out_by on Reaction to dedicated reactor equipment. This semantic
distinction separates analytical instruments (Device) from reaction vessels
(Reactor) in the carried_out_by relationship.

reactor geometry and operating mode.
