What the pipeline does

• SAST (Semgrep, CodeQL, Ruff), dependency scanning (pip-audit, Safety, OSV Scanner), container scanning (Trivy, Grype).
• SBOM generation and provenance attestation (SLSA) for every build artifact.
• Docker image signing with Cosign (keyless) and automated signature verification before deployment.
• Multi-architecture builds (linux/amd64, linux/arm64) with GitHub Actions caching.
• Automated Quality Gate aggregating tests, coverage (75%+), strict lint (mypy strict mode) and security results.
• Dependabot automation with differentiated patch/minor/major rules and controlled merge by dependency type.
• Production CD with staging validation, smoke tests and rollback notification on failure.
