feat(tui): observable wizard engine with config-first work queue

Unify Save/startup flows behind WizardEngine with dynamic WorkQueue,
config-first writes, nested dep discovery, streamed process logs, and
queue panel UI. Split bridge config/package.json writes and force
catalog refresh when trusted orgs change.
