test: remove skipped tests requiring external @socketsecurity/registry module

Remove 6 skipped tests that depend on @socketsecurity/registry:
- resolveRegistryPackageName describe block (4 tests)
- PackageURL lazy loading test
- scoped package name conversion test

These tests cannot run without the external module and were
permanently skipped, providing no value in the test suite.

Test count: 78 tests (6 skipped) → 72 tests (0 skipped)
