* feat(onboard): guided onboarding becomes the custodian flow
Question zero asks for discovery consent up front (full access recommended,
guarded asks once or configures manually; persisted as wizard.accessMode and
honored on reruns). Discovery quietly collects auto-ladder failures into one
summary with details behind 'See other options', quips about detected coding
agents, and announces the working route as a default with an easy undo.
After inference and the memory offer (skipped when discovery was declined),
fresh installs auto-apply the standard setup plan and hatch the agent
directly in the terminal; configured installs (pre-existing model or gateway
config) stay verification-only and never reinstall or restart the Gateway
service. Setup-apply failures fall back to the conversational chat.
Remote-gateway onboarding keeps its legacy chat handoff explicitly.
