 Select `multi-work` in a verified live Herdr root checkout to delegate local retrieval

+to `fast-lo` and independent work to `coordinate` children in either the current root
+checkout or new Herdr worktrees.
 It is primary-only and, like `coordinate`, uses the `deep-lo` model and effort,
 falling back to `good-lo` when `deep-lo` is unavailable. Clients viewing the
 same eligible location can see it; eligibility is revalidated before creation.
 
 Configure `experimental.subagent_depth: 2` at the root and worktree locations.

-coordinate tasks and retains native session/job handling. See [usage, permissions,
+For new coordinate tasks, omit `worktree` to share the current root checkout, or pass
