- add src/soup_cli/py.typed (PEP 561); verified it ships in the built wheel
- add .pre-commit-config.yaml (ruff lint+format + standard file-hygiene hooks)
- add mypy>=1.8.0 + pre-commit to the [dev] extra; lenient [tool.mypy] config
- add a non-blocking type-check CI job (mypy, continue-on-error: true)
- add CHANGELOG.md (Keep a Changelog; [Unreleased] + link to GitHub Releases)
- replace the ~221KB per-version security log in SECURITY.md with a concise policy
- raise the coverage gate 50% -> 77% (measured 79% on the suite; real-2 margin)
No version bump: hygiene/docs only — rides into the 0.71.0 deps-split release.
