Claude fdb9ca6786 Add comprehensive security enhancements to build pipeline ...

Security Improvements:
- Fork PR Protection: Builds from forks require manual 'safe-to-build' label approval
- Trivy Vulnerability Scanning: Scan all images for CRITICAL/HIGH vulnerabilities
- SHA-Pinned Actions: All GitHub Actions pinned to specific commits for supply chain security
- SBOM Generation: Generate Software Bill of Materials for all builds
- Provenance Attestation: Record build provenance for supply chain verification
- Security Events Upload: Upload scan results to GitHub Security tab
- Platform Optimization: Single-platform builds for PRs for faster feedback

Additional Security:
- Created SECURITY.md with vulnerability reporting process and security practices
- Added Dependabot configuration for automated dependency updates
- Limited permissions model (contents:read, packages:write, security-events:write)
- No registry push from PR builds (load-only for security scanning)

This addresses concerns about malicious PR builds by:
1. Requiring manual approval for fork PRs
2. Scanning all images before they could be pushed
3. Preventing PR builds from pushing to registry
4. Using verified, SHA-pinned actions
