[BUG] CLI SAMM2AASX: command fails with infinite recursion error during XML serialization

[o-muzyka]

How: List of performed steps

1. Create or use an existing valid Aspect Model file (e.g., TestAspect.ttl)
2. Run the SAMM CLI command to generate AAS: samm aspect TestAspect.ttl to aas
3. Command fails with StackOverflowError

What: Actual result vs expected result

Actual result:

• Command throws AasGenerationException with nested SerializationException
• Root cause: JsonMappingException: Infinite recursion (StackOverflowError)
• The circular reference occurs in DefaultAssetAdministrationShell["submodels"]->ArrayList[0]->DefaultReference["type"]
• The AAS file is not generated

Expected result:

• Command should successfully generate an AAS submodel template in XML format
