v0.1.2

Fixed

• The release workflow set io.modelcontextprotocol.server.name itself, in
  the old spelling, and what it sets wins over the Dockerfile's LABEL. So
  0.1.1 shipped an image that still carried the lowercase name and the
  registry refused it a second time. All four places that name the server
  now agree, and ServerManifestTest fails the suite when they drift:
  nothing else notices, because the image builds and pushes either way and
  the refusal only arrives at publishing time, by which point the label is
  baked into a released image.
