Document MethodRef overload signatures in the sample library model #1016

[AzazelSensei]

The sample library model only showed one MethodRef. Overloads need a separate entry each, and the signature has no spaces after commas. A space after the comma is why only one overload matched in #1016.

I added a two-argument isEmptyOrNull overload to the sample and a matching MethodRef so that shows up next to the existing one.

Fixes #1016

Summary by CodeRabbit

• New Features
  • Added an enhanced empty-or-null check that can optionally trim surrounding whitespace before evaluating a value.
  • Existing behavior remains unchanged when trimming is not requested.
  • Added support for checking strings with the new trimming option in sample usage.
• Bug Fixes
  • Improved handling and recognition of the overloaded empty-or-null check so both supported forms are evaluated correctly.

Walkthrough

Added StringUtils.isEmptyOrNull(CharSequence, boolean) with optional trimming. Added MyClass.checkModelTrim to call the overload with trimming enabled. Updated ExampleLibraryModels.nullImpliesTrueParameters() to register both isEmptyOrNull overload signatures and document the required MethodRef formatting.

Merge Risk: ⚪ Minimal · up to fd3ef

The change adds and models a sample overload without affecting production behavior. The PR is merge-ready after normal review, with a non-blocking follow-up to add Javadocs for the new methods.
