## lex/Token-design

Token is a dataclass with `kind: str` and `value: Any`.
- NUMBER tokens carry int or float value (int if no dot, float otherwise).
- All other tokens carry the literal character as value (e.g. PLUS has value '+').
- EOF token carries value None.

Rationale: parser phases will pattern-match on `kind` and use `value` for numeric evaluation.
