Summary

Makes assembly/type discovery resilient so a single type that cannot be loaded no longer crashes application startup.

Fixed

Type discovery (ContractToImplementorsMap) no longer aborts the whole scan — and the process — when inspecting a type whose base or interface types throw TypeLoadException (for example when a referenced assembly resolves to a version that no longer contains a referenced type). The unloadable type is skipped and the remaining types are still discovered.
ProjectReferencedAssemblies now tolerates assemblies whose DefinedTypes fail to enumerate, matching the existing behavior of PackageReferencedAssemblies.
