docs(agentydragon): add worktree helper script and branch convention to README

agentydragon/README.md

 Tasks live under `agentydragon/tasks/` as individual Markdown files. Please update each task’s **Status** and **Implementation** sections in place rather than maintaining a static list here.
 
+### Branch & Worktree Workflow
+
+- **Branch convention**: work on each task in its own branch named `agentydragon/<task-id>-<task-slug>`.
+- **Worktree helper**: run `create-task-worktree.sh <task-id>-<task-slug>`
+  in `agentydragon/tasks/` to create or reuse a worktree at
+  `agentydragon/tasks/.worktrees/<task-id>-<task-slug>` off the `master` branch.
