Merge step (b): carry in local-only files at original paths

Brings 47 local-only files from backup-local-main into the merge-upstream
branch at their pre-rename paths. Subsequent steps will rename these to
the ce-* convention and port shared-file merges.

  weekly-shipped, proof-push, ship-it, story-lens, sync-confluence,

  upstream-merge
- Custom agents: design-conformance-reviewer, tiangolo-fastapi-reviewer,
  zip-agent-validator, python-package-readme-writer, lint
- Custom commands: essay-edit, essay-outline, pr-comments-to-todos,
  resolve_todo_parallel, workflows/{plan,review,work}
- Local mods to ce-review/SKILL.md + review-output-template.md (will be
  ported to ce-code-review in a later step)
