Module extraction 

Centralized extraction helpers for ValueWord values.

These require_* functions provide a single source of truth for extracting typed values from ValueWord, returning descriptive VMError on type mismatch. They replace scattered ad-hoc patterns like:

let s = nb.as_str()
    .ok_or_else(|| VMError::TypeError { expected: "string", got: "other" })?;
