Add file-based Bubble, Stripe, and OpenRouter importers; usage attribution,
cost allocation, pricing simulator, credit wallets, and recommendations in the
dashboard API. Document whynot-design UI workflow and archive the finished
workplan with all ten tasks marked done.
Set bootstrap workplan active and finish all tasks: refine SCOPE.md and
README.md, add Dev Workflow and credential routing to AGENTS.md, propagate
.claude/rules/credential-routing.md, and document early-phase verification
commands (fix-consistency, registry sanity check).
