chore: add hanzo-agentic to workspace; exclude hanzo-sovereign (broken ml-dsa dep)

- hanzo-agentic — proper [lib] section with path = src/network.rs; included
  in workspace members.
- hanzo-sovereign — references `ml-dsa = "0.6"` which doesn't exist on
  crates.io (only 0.1.0-rc.* prereleases). Excluded until upstream releases
  a stable 0.x line.
