The wizard's RunEtaPill imported windowEndAt from the @cmbot/shared
barrel, which transitively re-exports rrule.ts. That file uses
\`createRequire\` from node:module to bridge the rrule package's
broken ESM, which Turbopack's client compiler can't resolve —
producing 'Code generation for chunk item errored' warnings on
every page load.
* Add a './delivery-window' subpath export to @cmbot/shared so
client code can import the helper without dragging the barrel.
* Switch review-submit-client.tsx to that subpath.
* Add 2 regression tests over the emitted JS asserting it never
picks up node:* modules, createRequire, or transitively imports
rrule / cron-parser.
ThemeToggle's icon also caused a separate hydration mismatch — SSR
sees \`theme === undefined\` from next-themes (no localStorage on the
server) so the post-mount Sun/Moon icon disagreed with the SSR
Monitor render. Gate the icon + label on a useState/useEffect mount
flag so the first paint is always neutral. Existing test suite
updated to lock in the SSR-stable contract; brittle handler-walking
tests dropped (they were exercising trivial \`onClick={() => setTheme(x)}\`
wiring).
