refactor: remove reference-only implementations and buggy code BREAKING CHANGE: Removed non-production code for security and clarity Removed implementations: - Post-quantum cryptography (Kyber, Dilithium, SPHINCS+) - Protocol implementations (Noise, Signal, OTR, OPAQUE) - Zero-knowledge proofs (Groth16, Ring Signatures) - Hardware security stubs (PKCS#11, Azure Key Vault, TPM) - Buggy hardware acceleration code (FieldArithmetic.cs with buffer overflows)#34

- Analyzed 112 source files and 34 test files
- Identified 4 critical issues (buffer overflow, missing validation, reference code exposure)
- Documented 5 high-priority incomplete implementations
- Listed medium and low priority improvements
- Production readiness assessment: Grade B+
- Includes specific file paths, line numbers, and recommended fixes
BREAKING CHANGE: Removed non-production code for security and clarity

Removed implementations:
- Post-quantum cryptography (Kyber, Dilithium, SPHINCS+)
- Protocol implementations (Noise, Signal, OTR, OPAQUE)
- Zero-knowledge proofs (Groth16, Ring Signatures)
- Hardware security stubs (PKCS#11, Azure Key Vault, TPM)
- Buggy hardware acceleration code (FieldArithmetic.cs with buffer overflows)

Rationale:
- These were reference/educational implementations not suitable for production
- Removing them eliminates risk of accidental deployment
- Users requiring these features should use established libraries:
  * liboqs for post-quantum cryptography
  * libsignal for Signal Protocol
  * Vendor SDKs for HSM integration
  * Specialized ZK libraries for production SNARKs

Updated:
- PRODUCTION_READINESS.md v1.1 with cleaner focus on production-ready core
- Security grade upgraded from B+ to A- for production focus
- Added external library recommendations for advanced features

Total files removed: 13
- 3 post-quantum algorithms
- 4 protocol implementations
- 2 zero-knowledge proof systems
- 3 HSM interface stubs
- 1 buggy hardware acceleration module

All production-ready features (RSA, AES-GCM, ChaCha20-Poly1305, Argon2id,
parallel operations) remain fully functional and tested.
