Research direction

Search the MATLAB grammar's rules for property and function validation syntax, then reproduce the Account example to inspect how mustBeNumeric is tokenized. Update the relevant rule so validation functions receive the same token classification as function names, and verify the sample no longer produces storage.type highlighting.

Written by the indexing model from the issue text.

Description

Consider the following example:

classdef Account
    properties
        Balance (1,1) mustBeNumeric
    end
end

In this situation, mustBeNumeric is tokenized as a storage.type, but it would be more accurate to tokenize it the same as a function name.
