Error Handling Enhancement:
setTypesmethod to theNextflowMetaclass that throws anAbortOperationExceptionwith a clear error message if static types are enabled while using syntax parser v1, guiding users to setNXF_SYNTAX_PARSER=v2for static types support.With this PR the user will get a message sucha as the following:
Static types only available in syntax parser v2. Set NXF_SYNTAX_PARSER=v2 to enable static types. -- Check script 'module.nf' at line: 1 or see '.nextflow.log' file for more details
