modify captured variables. Implement `capture_upvalue` and `get_value`/`set_value` methods in the `VM` to handle these mutable upvalues. Refactor number parsing to support integers and floats Separate the `TokenKind::Number` into `TokenKind::Integer` and `TokenKind::Float`. Update the lexer to distinguish between integer and float literals. Update the parser to correctly map these new token kinds to their respective `Value` types. Add integration tests for parsing integers and floats, and for closure modification of captured variables.
