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).
Convert legacy AdaptivePricing-MVP-Workplan.md into
ADAPTIVE-WP-0002-economic-observatory-mvp.md with ADR-001 frontmatter,
eight sprint task blocks, and State Hub workstream registration. Mark
bootstrap task T03 done after seeding the first implementation workplan.
