Optional ReadonlyignoreKeep each step's QuickPick/InputBox open when focus moves elsewhere.
Defaults to true — without it, briefly switching windows mid-wizard
silently discards everything answered so far.
Optional ReadonlyloggerReceives step-transition debug logs.
Optional ReadonlyshowShow native step/total-step numbering (VS Code's own "1/3" indicator).
Optional ReadonlysignalAborting cancels the wizard: the open step hides and run resolves cancelled.
ReadonlytitleTitle shown for steps that don't set their own opts.title.
Optional ReadonlyuiThe quick-input surface to build steps on. Required when the builder was
created without a default (the root wizard() export binds VS Code).
Options for WizardBuilder.run.
