Replace # noqa: SVC-006 with # SVC-006 to avoid ruff warnings about
unknown codes. Updated architecture validators to match the new format
by checking for the code string directly instead of the noqa: prefix.

Move 9 init/seed scripts into scripts/seed/ and 7 validation scripts
(+ validators/ subfolder) into scripts/validate/ to reduce clutter in
the root scripts/ directory. Update all references across Makefile,
CI/CD configs, pre-commit hooks, docs (~40 files), and Python imports.
