): value is ExpectItExecutor<Subject>
Type guard for ExpectItExecutor functions.

This function checks if a value is an ExpectItExecutor function created by expect.it(). ExpectItExecutor functions are special functions that contain assertion logic and are marked with an internal symbol for identification. They are used in nested assertions within "to satisfy" patterns and other complex assertion scenarios.
Type Parameters
- Subject extends ZodType<unknown, unknown, $ZodTypeInternals<unknown, unknown>> = ZodUnknown
  The subject type that the executor function operates on
Parameters
- value: unknown
  Value to test
Returns value is ExpectItExecutor<Subject>
true if the value is an ExpectItExecutor function, false otherwise
Example
```
const executor = expect.it('to be a string');
if (isExpectItExecutor(executor)) {
  // executor is now typed as ExpectItExecutor
  // Can be used in satisfaction patterns
}
```
