Module eval 

Template evaluation engine.

The evaluator walks a parsed Template AST and produces a string output. It resolves variables and dispatches processor/command calls through the provided EvalContext and Registry.

Temporary scopes (e.g. foreach loop bindings) are managed internally. The host’s EvalContext only sees named scope operations like "global" and "local".
