refactor: use loop pattern for include/exclude tests

Refactor tsconfig_include_exclude tests to follow existing codebase
patterns used in tsconfig_paths.rs and extensions.rs.

Changes:
- Consolidate 25 individual test functions into 8 focused tests
- Main test uses data-driven array with loop (68 test cases)
- Separate tests for special behaviors (empty arrays, inheritance, etc)
- Better error messages with fixture name, file path, and description
- More maintainable - easy to add new test cases

All test coverage preserved. All 19 fixtures still tested.
