Bump Microsoft.Extensions.AI to 10.5.1; rewrite version-matrix.md

- Directory.Packages.props: 10.5.0 -> 10.5.1 for all five M.Extensions.AI packages
  (patch bump confirmed via NuGet API 2026-05-03; all other Critical-5 pins
  remain at their current stable ceiling)
- docs/version-matrix.md: full rewrite from stale 0.3.x-preview baseline to
  current 1.x stable pins; now mirrors Directory.Packages.props exactly
