v1.0.1

Changed

• Docs only (no public-surface change): CONTRIBUTING.md makes lint + format an
  explicit step in the dev loop, and CLAUDE.md / CONTRIBUTING.md add the
  adversarial-diff review as the final pre-commit step — aligning this repo
  with the family-wide dev-loop convention.
• CI: bump the GitHub Actions group (3 updates) via Dependabot.

v1.0.0

First stable release — the public surface is considered stable; this is the v1.0
milestone for the Claude routine family.

Added

• Self-contained trunk-on-main CONTRIBUTING.md, LICENSE (MIT) + license
  field, .github/workflows/release.yml (tag -> GitHub Release) and
  .github/dependabot.yml (weekly pip + actions PRs).
• Code-coverage gate: pytest-cov, fail_under = 80 in [tool.coverage].
• Ruff lint + format gate ([tool.ruff]), run in CI before the tests.

Changed

• CI: ruff check + ruff format --check before pytest; actions/checkout -> v5.
• Code reformatted by ruff format (no behaviour change); .gitignore ignores
  coverage artefacts.
