Summary

Explain which NeuralForecast models reject exogenous variables and how to resolve the "does not support future exogenous variables" exception.

Changes

• PatchTST page: note that exogenous lists are accepted for API consistency but raise an exception; point to supported models.
• Exogenous variables guide: replace the "all models" claim with a note pointing to the overview table and the fix.
• Models overview: footnote 6 now explains the dash and the exception raised for unsupported lists.

Context

Assistant could not explain the PatchTST future exogenous exception from the docs. The PatchTST parameter table lists futr_exog_list, but the overview table marks it as having no exogenous support.
