typecheck: clarify extra CHECK TYPE tokens

 - typed variables such as `SET score NUMBER 10`
 - `TYPE OF` and `CHECK TYPE`
 - `CHECK TYPE` gives a direct repair hint when the learner forgets the `IS` keyword, for example `CHECK TYPE score` reports `CHECK TYPE needs IS. Try: CHECK TYPE score IS NUMBER.`
+- `CHECK TYPE` rejects extra words after a valid expected type with a direct repair hint, so `CHECK TYPE score IS NUMBER TEXT` explains that only one type belongs in the check
 - `CHECK TYPE` rejects unknown expected type names with a beginner-facing list of supported types
 - typed list/map checks through `claro typecheck`, including a nested `LIST OF MAP` insertion example
 - simple function and object-method return checks with `TEACH name ... RETURNS TYPE`, including learner-facing diagnostics for unknown declared return types, mismatched or not-yet-inferable `RETURN` expressions (including method-specific diagnostics naming the class and method, with modern and compatibility method coverage), empty `RETURN` statements, declarations that contain no `RETURN`, and declarations whose only return is inside an incomplete conditional; `RETURNS` is case-insensitive like other Claro keywords and has positive coverage in both modern and compatibility function forms, including lowercase compatibility declarations and lowercase compatibility method declarations, plus a lowercase compatibility-method mismatch diagnostic; `CHECK TYPE` parameter metadata also informs arithmetic return-expression checking, including method return expressions; positive function-return coverage includes numeric multiplication; compatibility methods now have dedicated positive numeric addition, subtraction, division, and multiplication return fixtures plus compatibility addition, subtraction, division, and multiplication diagnostic fixtures; NUMBER return diagnostics name a known TEXT operand and arithmetic operation instead of hiding the cause behind a generic mismatch, with focused addition, subtraction, multiplication, and division coverage for functions and methods; typed methods can also return class-declared fields by simple name, with positive and mismatch coverage in both modern and compatibility method syntax
