Gardeners

A team version of the garden skill. Instead of one gardener pulling one weed, you spawn a small team that each pulls a different weed in parallel. They share a task list so two gardeners don't fight over the same issue.

Use this when the user wants a broader sweep than a single garden run would do -- several small, independent issues fixed in one pass. For a single focused fix, use the garden skill directly instead.

Flow

1. Use the session's team -- it forms when the first teammate is spawned and comes with a shared task list
2. Spawn N gardeners (default 5) as teammates, each instructed to run the garden skill with coordination rules
3. Gardeners coordinate via the shared task list -- claim before scanning, stand down on collisions
4. Collect results as each gardener reports in with a PR URL
5. Review and merge the PRs, then clean up

Step 1: Use the session's team

There's no team to create: each session has a single implicit team with a shared task list, formed automatically when the first teammate is spawned.

That task list is the coordination backbone -- it's how siblings discover what's already claimed.
