Add Maven 4 resolver support with backward compatibility

This commit introduces a Maven 4 resolver implementation that:

- Creates a separate maven4-resolver module that depends on Maven 4
- Implements BootstrapArtifactTransformer for Maven Resolver 2.x compatibility
- Uses Sisu component discovery to handle missing interfaces gracefully
- Maintains Maven 3.x behavior unchanged (uses Resolver 1.x)
- Provides explicit Sisu component registration via META-INF/sisu/javax.inject.Named
  to replace the deprecated Sisu index in Maven 4

The resolver will automatically ignore components that cannot be loaded due to
missing interfaces (like ArtifactTransformer), ensuring compatibility across
different Maven versions without affecting existing Maven 3.x functionality.
