fix: resolve Java wildcard imports from JBang dependencies

[maxandersen]

Fixes #163.

Problem

Java wildcard/on-demand imports (import example.*) did not resolve classes from JBang dependency JARs, while explicit imports and fully-qualified names worked.

Root cause (diagnosed by JetBrains — IDEA-393077)

JBangLibraryProvider exposed the classpath as a plain SyntheticLibrary. Only a JavaSyntheticLibrary contributes its roots to PackageIndex (fileSetsByPackagePrefix); any other SyntheticLibrary gets DummyWorkspaceFileSetData, so JavaFileManagerImpl.findPackage("example") returns null. On-demand imports whose reference resolves to null contribute nothing, leaving wildcard-imported types unresolved. Explicit imports/FQNs keep working because they use JavaFullClassNameIndex, which does not depend on the package-prefix storage.

"Make JBangSyntheticLibrary extend JavaSyntheticLibrary instead of SyntheticLibrary." — Mikhail Pyltsin, JetBrains

Fix

JBangSyntheticLibrary now extends JavaSyntheticLibrary(comparisonId, sourceRoots, binaryRoots, excludedRoots).

Test

JBangLibraryProviderTest.testProviderExposesJavaSyntheticLibraryForPackageIndex asserts the provider returns a JavaSyntheticLibrary — red before the change, green after. Full suite passes.
