Post-apply the wizard now renders real Studio actions instead of CLI
text: a start-hub button that polls until the daemon answers,
per-module install buttons (capability-name install via the hub's
store index) with done/progress states, and an open-the-starter-flow
button that navigates to the Flows page. Regulated plans explain in
plain language that modules come from a signed source; the preview
offers 'allow installing from the public store' as one deliberate,
reversible switch that re-assembles the plan (allow_unsigned_modules).
Fresh installs (no config, no setup-plan.yaml) auto-open the wizard
once per run — the wizard IS the onboarding — and it steps back once
a setup exists. The welcome CTA is framed honestly ('get started in
3 questions'), and after the wizard closes the onboarding checklist
remounts, re-probes, and says what the assistant already covered
(profile line from setup-plan.yaml) instead of acting as a second,
disconnected onboarding surface.
