Security: Address OpenSSF Scorecard Alerts (#17)

This PR addresses several security and maintenance alerts:
- Resolves high-severity RUSTSEC-2024-0384 (instant crate)
- Pins Fuzzing Dockerfile base image to SHA
- Adds CODEOWNERS for review accountability
- Adds Semgrep SAST workflow
- Establishes CII Best Practices and Security Acknowledgments

+# OpenSSF Best Practices (CII) Adherence
+
+This document tracks the project's adherence to the [OpenSSF Best Practices Badge](https://best-practices.coreinfrastructure.org/) criteria.
+
+## Summary
+The anvomidav project is committed to following open-source security and quality best practices.
+
+## Change Control
+- **Public Repository**: All source code is hosted on GitHub and is public.
+- **Version Control**: We use Git for version control.
+- **Unique Versioning**: All releases use unique version identifiers (SemVer).
+
+## Reporting
+- **Bug Reporting Process**: Documented in `CONTRIBUTING.md`.
+- **Vulnerability Reporting**: A clear `SECURITY.md` file defines the private reporting process.
+
+## Quality
+- **Automated Builds**: We use GitHub Actions for automated builds and CI.
+- **Testing**: Automated test suites are integrated into the CI pipeline.
+- **New Features**: New functionality is required to have associated tests.
+
+## Security
+- **Secure Development**: We use automated security scanners (CodeQL, Trufflehog, ClusterFuzzLite).
+- **Dependency Pinning**: GitHub Actions and critical dependencies (including Fuzzing Dockerfiles) are pinned to specific versions/SHAs.
+- **No Hardcoded Secrets**: Scanned via `trufflehog` and `gitleaks`.
+
+## Best Practices
+- **SPDX Headers**: We use SPDX license identifiers in all source files.
+- **Code Review**: All changes require a pull request and code review before merging to `main`.
