mcp: registry-ready (server.json oci/ghcr, v2.6.0/43 tools, Dockerfile label, OIDC publish) (#270)

Fix stale server.json: version 2.0.0->2.6.0, 36 tools->43, replace the invalid
'github' registryType with 'oci' (ghcr.io/perseus-computing-llc/mimir), drop a
non-existent curl-install line. Add the MCP ownership LABEL to the Dockerfile
(matches server.json name) and an OIDC publish workflow for the MCP Registry.
