Subject: [PATCH] Load configured Modelica libraries on startup

Accept library paths from initialization options via both modelicaPath and libraries. Filter the configured values to non-empty strings, resolve them to file URIs, and load each library during server initialization so configured Modelica paths are available to the analyzer.
