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).
Move the framework PRD from specs/ to docs/ and remove the misplaced
specs/ directory. Document repository layout in AGENTS.md and SCOPE.md:
generic material in docs/, project-specific MVP artifacts in
projects/coulomb-pricing/, execution tracking in workplans/.
