Add VORTEXRAG — Production-ready 7-Layer RAG Framework

[vignesh2027]

VORTEXRAG is a production-ready 7-layer RAG framework designed for LLMOps use cases.

Why it matters for LLMOps:

• 11 domain presets (medical, legal, financial, cybersecurity, scientific…) for plug-and-play deployment
• Formal faithfulness guarantee (ΔR ≤ 0.15) — measurable SLA for production
• 185ms P50 latency at full 7-layer precision
• 229 tests passing across Python 3.10–3.13
• CI/CD with GitHub Actions, Codecov coverage

Benchmark: EM 74.8, F1 82.6, Faithfulness 0.94 — best across 8 evaluated systems
