The plan strip header has not emitted `<done>/<total> tasks · <n> in progress`
since #740 replaced it with `·`-joined per-status counts. Four sites still
quoted the old string: plan-summary.ts's module JSDoc, ui-conversation's
README pair, and the web-todo-display note pair.
The parallel-in-progress note's regression example mixed a four-item plan with
an eight-item row reading, and built-boot.snapshot.ts still called itself the
only test loading the built bundles.
