Perf: Tool-Konfigurationsauflösung in _create_transformation_job gecacht

Browse Source 
Die 5 linearen Lookups (java_vm, saxon_jar, apache_fop, diff_pdf, xsl_dir)
werden jetzt nur einmalig pro Projekt aufgelöst (_get_cached_project_tools).
Bei Batch-Transformationen entfällt das wiederholte Durchsuchen der Listen.
