Bering v0.3.1

v0.3.1

Fixed

• Schema publishing is now a completed part of the shipped release path rather than a post-release manual recovery step.
• The GitHub Pages schema publication workflow now resolves pinned schema constants and step outputs correctly for both tag-driven and manual runs.
• README release badges now match the Sheaft header pattern and point at the current Bering release line.
• Release-facing docs now consistently describe v0.3.1 as the current product line carrying the published 1.1.0 schema contracts.
