v1.0.0

First release, by Louis Wright.

• Required sections (install, usage, license by default; configurable with aliases), empty sections, title and heading-level checks.
• Install command checks: wrong or renamed package names, stale pinned majors, deprecated --save, bower, global installs of packages without a bin, missing CLI documentation.
• Badge checks: shields.io/npm/GitHub badges pointing at another package or repo, dead CI services (travis-ci.org), insecure http:// images; optional live check with --check-links.
• Relative link and image targets, in-page #anchor links using GitHub's slug rules, placeholder text, license mismatch with package.json, very short READMEs.
• Text/JSON/SARIF/Markdown output, --fail-on, exit codes 0/1/2, allowlist with expiry, severity overrides.
• Composite GitHub Action with job summary.
