Rename change-request.machine.ts's bare State/Msg to ChangeRequestState/
ChangeRequestMsg (the last machine not context-prefixed), document the
createStore-is-the-idiom + naming convention in CLAUDE.md §3, and add the
Foundations/State Machines (TEA) curriculum page. The wizard pages already
wired createStore (confirmed by reading each and by git log) -- the WP's
"hand-wired signal(model)" premise was stale; recorded as a deviation.
