Keep quality gate script visible to mypy

The CI mypy step scans the repository root and the new tests import the gate as scripts.check_test_evidence. Without a package marker, mypy sees scripts/check_test_evidence.py under two module names and exits before coverage can run.

Constraint: Existing CI runs make mypy-check before make coverage on every push.

Rejected: Excluding scripts from mypy | the quality gate code should remain type-checkable with the rest of the repository.

Confidence: high

Scope-risk: narrow

Directive: Keep scripts/__init__.py if tests import repository scripts as package modules.

Tested: make mypy-check

Tested: uv run pytest tests/unittests/test_quality_gate.py

Tested: make coverage

Not-tested: GitHub-hosted CI rerun is pending after push.
