# Purpose: Presentation-layer composition root for the Noveler MCP server.
#          Centralises the legacy runtime logic so that mcp_servers.noveler.main
#          can stay as a thin delegate.
# Context: Imported by the legacy entrypoint and bootstrap wrappers. Depends on
#          noveler.infrastructure (console/logging/path/artifact services) and
#          MCP runtime components.
