Task-list tools for in-process teammates are off by default in this build.

What

The team context block injected for teammate agents now adds the task list path and the instruction to check it only when task-list tools are actually available, and the in-process teammate agent only receives those tools in the same case. Availability is off by default in this build.

Details
Evidence

Check the task list periodically. Create new tasks when work should be divided. Mark tasks resolved when complete.

Strings lifted out of the shipped bundle, so the claim above can be checked against them.
