  Naga ships as a 7-plugin marketplace. Each sub-plugin owns one engine or
  one orthogonal concern. The `full` meta-plugin lists them all as
  dependencies so one install pulls in the whole chain.

  Finish in Claude Code with TWO commands:

    /plugin marketplace add enchanter-ai/naga
    /plugin install full@naga

  Verify with:   /plugin list
  Expected:      full + 6 sub-plugins installed under the naga marketplace.
