docs: update title and A/B comparison with reproducible BRAF evidence

Title: Terraphim Clinical Pipeline: Graph-Based Safety Gates for MedGemma
-- From Class Suggestions to Specific Drug-Dose Evidence

Replace EGFR 800mg anchor (stochastic) with reproducible BRAF case:
raw MedGemma says "BRAF inhibitor (e.g., ...)" while KG-grounded
produces "Vemurafenib 450mg once daily". Add CYP2D6 wrong-drug case.
Include fresh A/B comparison log from 2026-02-24 GPU run as evidence.

-The raw LLM gets the right drug but hallucinates a **10x dosing error**. An oncologist receiving "Osimertinib 800mg" may catch this, but automated clinical decision support systems may not. The knowledge graph constrains the model to the evidence-validated dose. In a second case (BRAF melanoma), raw MedGemma produced "BRAF inhibitor (e.g., Dabrafenib + Trametinib)" -- vague hedging -- while the KG-grounded version produced "Vemurafenib 450mg daily" with a specific drug from the treatment graph.
+The BRAF case is the most reliably reproducible: raw MedGemma consistently hedges with drug class names ("consider BRAF inhibitor") instead of actionable prescriptions. The knowledge graph narrows this to a specific drug from the evidence-validated treatment subgraph. The CYP2D6 case shows the raw model substituting a different drug entirely, while KG grounding keeps the recommendation within the context-appropriate drug set. The EGFR case has shown stochastic dosing errors (800mg in one run, correct 80mg in another) -- exactly the kind of non-determinism that makes raw LLM output unsuitable for clinical decision support.
 
 ### Why This Matters
