BREAKING CHANGE

• the in-tree MCP server is removed from engrava. The engrava[mcp]
  optional-dependency extra, the in-engrava engrava-mcp console script, and the
  in-tree server module are gone; a plain 'pip install engrava' is unaffected. The
  server moved to the standalone engrava-mcp package (uvx engrava-mcp), which
  consumes engrava's public API. Migrate per the docs/upgrade.md 0.4 -> 0.5 notes.
