Module context 

XPath 1.0 Evaluation Context (§25).

The evaluation context holds the state required to evaluate an XPath expression: the current document, context node, context position/size, variable bindings, namespace declarations, registered extension functions, and recursion-depth tracking.

UPSTREAM-PARITY

Mirrors xmlXPathContext from libxml2 with additional Rust-side state for variable/function resolution and safe recursion guards.
