update version to 0.6.0

What's New

Added

• Migration Safety detector — scans all migrations/ directories and flags
  operations that carry deployment or data-safety risk: RemoveField,
  RenameField, AddField without a default on a NOT NULL column,
  RunPython without atomic = False, and RunSQL.

Fixed

• missing_service_layer detector no longer false-positives on DRF override
  methods (get_queryset, perform_create, get_context_data, etc.)

Installation

pip install django-arch-check==0.6.0
