Summary

Moves developer-only local runtime/bootstrap entrypoints into dev/local-runtime/ while preserving the public npm command surface.

• Updates package.json command targets while preserving command names.
• Updates targeted tests, validation references, and Project Instructions/backlog status.
• Does not move API/server app files or www/ browser files.
