## Title

    Proposed fix: [Python 3.14] AttributeError: module 'ast' has no attribute 'Num' (ast.Num/Str/Bytes/NameConstant/Ellipsis removed; visit_Num silently never called)

## Body

    Recommended action: Use ast.Constant and inspect type(node.value); implement visit_Constant; replace .n/.s with .value. For third-party packages upgrade (e.g. simpleeval/inflect releases supporting 3.14) or use Python 3.13.
    
    Option: Switch to ast.Constant / visit_Constant [evidence: official_recommended_action]
    Applies when: Python>=3.8 code
    Steps:
    1. isinstance(node, ast.Constant) and isinstance(node.value, (int, float, complex))
    2. rename visit_Num/visit_Str to visit_Constant with type dispatch
    3. node.n/node.s -> node.value
    Expected: Works on 3.8-3.14
