[FEATURE] Add a new label for internet-connected modules

Is your feature request related to a problem? Please describe

For HPC systems where compute nodes do not have internet access (examples: tars, UPPMAX, Atlas), modules that attempt to contact the internet fail when launched by Nextflow using the job scheduler. This includes modules such as

• ncbigenomedownload
• edirect/esearch (proposed)

Describe the solution you'd like

I suggest a new label -- something like process-requires-internet -- that goes on these modules requiring internet connectivity. Config designers could then ensure all internet-connected processes are run on nodes with internet access, or fail a pipeline containing one of these modules early.

Describe alternatives you've considered

Alternative: remove all internet-connected processes from this repository and put a statement in the docs that all processes must be able to be run offline. This is probably best from a pipeline reproducibility standpoint, but less practical from my point of view.

Additional context

No response

Start by reviewing the linked ncbigenomedownload module, the proposed edirect/esearch issue, and the referenced HPC configuration examples. Determine how a process-requires-internet label should be represented and where it must be applied; done means affected modules are identifiable so configuration designers can handle or reject them early.
