NOTEPAD: drop what is done, correct what was never true

A sweep against the code. Removed as resolved: the worker pool's `_running`
is keyed by (run, node) now, `WorkItem.kind` documents only the three kinds
that exist, `routeTree.gen.ts` matches its generator, and the host's Node is
well past the version the Vite 7 note was about. Removed as disproved: the
collector's redelivery branch is reachable — Redis reclaims an entry this
process is still running.

Corrected: the demo places six of the fifteen node types, not thirteen — the
count was the widget types. Narrowed to what is left: the header/config sync
now covers settings but only on an untouched scaffold and only one way; a
declared flow input is what the dashboard-input node asked for; the flow
boundary already refits the canvas where node ports do not.

The Playwright hazard is not resolved — both names still resolve to
production — and the fix as written is incomplete: `VITE_API_URL` has to be
overridden to `http://` or every setup call fails the TLS handshake.

Also: one `asText` instead of two, and the queue docstring no longer refers
to a node item that never existed.
