Restore compile-time resolution for source launch

[DanielThomas]

Summary

• restore --compile-time for compilation that is not represented by a module source path, such as Java source-file launch
• include inherited requires static transitive dependencies of compilation roots while continuing to omit plain static dependencies of compiled binaries
• place compile-only dependencies on the generated module path without adding them to runtime roots

This addresses the source-launch use case reported in Netflix/ja#77.

Testing

• ja test --all (555 tests)
• ran the JUnit 6.1.3 compact source-file example with the generated argument file; it completed without warnings and included org.apiguardian.api and org.jspecify
