Fix Missing Identifier References

[BenBaryoPX]

This pull request improves the handling of identifier references in the mapIdentifierRelations function and enhances test coverage for identifier resolution in parsing tests.

Improvements to identifier reference handling:

• src/flast.js: Updated the mapIdentifierRelations function to combine references from both scope.references and scope.variableScope.references into a single array, ensuring more comprehensive mapping of identifier relations.

Enhancements to test coverage:

• tests/parsing.test.js: Modified the test case for verifying identifier references to include a more complex switch statement with a case block, improving the robustness of the test.

• [nitpick] The updated test case now covers a basic switch-case scenario. Consider adding tests with multiple cases and a default clause to further validate the identifier reference mapping.

const code = `let a = 1; switch(a) {case 1: a;}`;

src/flast.js:237

• [nitpick] Consider adding an inline comment explaining the rationale for merging both scope.references and scope.variableScope.references to improve code maintainability.

const references = [...(scope.references || []), ...(scope.variableScope?.references || [])];
