The starter README said tasks-app is the running example for M1 and M2 only.
In reality it's used from M1 through the capstone: agent-driven edits in M4,
worktrees drive it in M7, the review lab pastes a patch onto it in M10, and
so on. Tighten the note to reflect actual scope.
Ports back the same change already merged on the GitHub mirror
(recklessop/ai-workflow-course#2) so it survives the next Gitea -> GitHub sync
instead of getting overwritten.
