Overview

Operator catalogue. Each PDF content operator (q, m, Tj, ...) is implemented by a subclass of Operator::Base that registers itself in REGISTRY at file load.

Adding a new operator = adding one subclass + register. No switch edits (open/closed). Mirrors the postscript gem's Model::Operators pattern.
