Defer Revit work and remove Dynamo scripts

Further Revit exchange will use the CSV export/import of the Linear
plugin instead of Dynamo, as preferred by the internal Revit/CAD
steering committee. Mark the Revit documentation as deferred and remove
the Dynamo diagnostic scripts, which stay reachable through the tag
archive/dynamo-vorueberlegungen.

 ## Revit / CSV External Model Work
 
+Status: further Revit work (editor assignment UI, follow-up import, return
+export) is deferred and will be tackled later. When it resumes, the exchange
+stays CSV-based and uses the CSV export/import of the Linear plugin in Revit.
+The internal Revit/CAD steering committee prefers this over manipulating the
+model directly through Dynamo. Do not start Dynamo, Revit API or JSON
+transport work. The Linear CSV layout is not yet known: check a sample export
+against the existing project CSV configuration before changing the parser.
+Earlier Dynamo considerations are archived in
+`docs/archive/revit-dynamo-leistungsbilanz-integration-konzept.md`; the
+removed diagnostic scripts remain reachable through the git tag
+`archive/dynamo-vorueberlegungen`.

 `docs/spec/revit-csv-integration-requirements.md` as the detailed source of
 truth together with the current architecture documents.
