Module vtable 

Vtable for type-erased report operations.

This module contains the ReportVtable which enables calling handler methods on reports when their concrete context type C and handler type H have been erased. The vtable stores function pointers that dispatch to the correct typed implementations.

This module encapsulates the fields of ReportVtable so they cannot be accessed directly. This visibility restriction guarantees the safety invariant: the vtable’s type parameters must match the actual report context type and handler stored in the ReportData.

Safety Invariant

This invariant is maintained because vtables are created as &'static references via ReportVtable::new, which pairs the function pointers with specific types C and H at compile time.
