Pull Request Overview

This PR improves URL handling for cases where the root document is located at the "/" path, ensuring that the expected trailing slash behavior is correctly applied. Key changes include:

• Updated getParentPath logic in src/shared/url-utils.ts for better trailing slash and parent path handling.
• Removed redundant trailing slash normalization in src/ogc-api/link-utils.ts to rely on the updated URL utilities.
• Adjusted tests in src/ogc-api/endpoint.spec.ts and src/shared/url-utils.spec.ts to verify the correct behavior with root and collection paths.

src/ogc-api/link-utils.ts	Removed code that appended a trailing slash for collections; now uses getParentPath output directly.

• [nitpick] Consider fixing the test description to properly close the parenthesis for clarity.

• [nitpick] The previous logic automatically appended a trailing slash for collections; please confirm that this change is intentional and that URL normalization is handled consistently.
