Google2Fa Laravel Package

Added

• Support for PHP 8.6 (beta) in the CI test matrix, with automatic fallback (continue-on-error) while the toolchain catches up
• Psalm static analysis alongside PHPStan, including the psalm/plugin-phpunit plugin so PHPUnit's TestCase hierarchy resolves correctly
• SECURITY.md, SUPPORT.md, and a Version Support policy documenting which branches receive fixes
• composer.json support block (issues/source/docs/security) and expanded keywords (totp, hotp, otp, mfa, rfc4226, rfc6238)

Changed

• Widened dev-tooling constraints: PHPUnit ~9|~10|~11|~12|~13, PHPStan ^1.0|^2.0
• Modernized CI: explicit PHP↔PHPUnit compatibility matrix, pcov coverage, updated action versions, added a legacy-stack verification job
• Simplified getTimestamp()'s division (credit: Michal Špaček, cherry-picked from #232)

Fixed

• Codecov upload no longer hard-fails CI when secrets.CODECOV_TOKEN is unavailable (e.g. on fork pull requests)
• Removed the dead code-quality job (Prettier/Node.js) that never ran against this PHP-only package
• Retired .scrutinizer.yml, which pointed at a coverage file no longer produced; Codecov already covers this

Security

• No behavioral change to secret generation, HMAC computation, or OTP verification — see docs/audit/9.x-ci-and-governance/03-src-security-review.md for the line-by-line review

⚠️ Breaking Change
