Robin Braumann d308f00de5 refactor(core): Preserve agent knowledge file rows in storage migration (no-changelog) 
Keep existing agent_files and binary_data rows instead of deleting them, so
the migration is a pure column swap and can be reverted. The binary_data
sourceType CHECK stays as-is, since narrowing it would fail on instances
that still hold legacy rows.
