fix: clarify task assignment flow in pact-task-tracking

Lead assigns tasks when spawning teammates — that's the default.
Self-claiming from TaskList is the exception for batch scenarios
(multiple teammates sharing a pool of tasks in the same domain).

 ## Task Self-Management
 
-You have direct access to Task tools. Use them to manage your own work:
+The lead assigns you a task when spawning you. Mark it in-progress and begin working immediately.
 
-- **TaskUpdate**: Claim unassigned tasks in your domain, mark tasks in-progress or complete.
-- **TaskList**: View team progress and discover unassigned tasks.
+- **TaskUpdate**: Mark your assigned task in-progress or complete.
 - **TaskCreate**: Create sub-tasks if your work expands beyond the original scope.
+- **TaskList**: View team progress. In batch scenarios (multiple teammates sharing a pool of tasks), use this to discover and claim unassigned tasks in your domain.
 
 ### Conventions
 
 - The team lead is always named **"team-lead"**.
-- Claim only tasks within your specialist domain. Do not claim cross-domain tasks.
-- When claiming an unassigned task, use `TaskUpdate(taskId, status: "in_progress")`.
+- When starting your assigned task, use `TaskUpdate(taskId, status: "in_progress")`.
 - When your task is done, use `TaskUpdate(taskId, status: "completed")` as part of your HANDOFF delivery (see section 8).
+- In batch scenarios only: claim unassigned tasks within your specialist domain. Do not claim cross-domain tasks.
