docs: align the Home lead and Security casing with the positioning style sheet
Home.md:3 — "…SDKs of Algenta — the governed AI decision engine." -> the README lead: "Python and TypeScript client libraries for Algenta — self-hosted building blocks for AI applications." Security.md:35 — "Algenta Engine entitlement/license enforcement" -> "Algenta engine entitlement/license enforcement".
