Estimated code review effort: 4 (Complex) | ~45 minutes Merge Risk: 🟡 Moderate · up to This PR adds new public AST representations and runtime fields, but current helpers disagree about how constant expressions are classified, including empty strings and literal conversion. That can cause incorrect downstream analysis or execution behavior, while the ignored runtime overlays require an explicit ownership and authority contract.

Handle empty ConstantValue::Str values as empty interpolations.
Expr::Constant can contain ConstantValue::Str(""), but is_non_empty_f_string returns true for every constant. Return false for an empty string value, consistent with Expr::StringLiteral.

Keep is_literal_expr() and as_literal_expr() consistent for Expr::Constant.
is_literal_expr() returns true for every Expr::Constant, but as_literal_expr() returns None because LiteralExpressionRef has no Constant variant. Remove Expr::Constant from is_literal_expr(), or add the required variant and conversion. Update the docstring to match.
