Subject: [PATCH] feat(dbschema): DbSchema-Contracts entfernen (#7)

DbSchemaReaderInterface und DbSchemaExporterInterface stammten aus dem
stillgelegten jardistools/dbSchema (2026-07-24, GitHub-Repo geloescht).
Nachfolge ist die Builder-Faehigkeit Schema-zu-DDL. Bestandspruefung
2026-08-12: kein Repo der Flotte importiert oder implementiert diese
Interfaces.

Bescheid Rolf 2026-08-12: Minor-Release im v1-Bereich, da noch nicht
publiziert genutzt.
