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.

Includes:
- Custom skills: john-voice, jira-ticket-writer, hugo-blog-publisher,
  weekly-shipped, proof-push, ship-it, story-lens, sync-confluence,
  excalidraw-png-export, python-package-writer, fastapi-style,
  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)

+Your workflow process:
+
+1. **Initial Assessment**: Determine which checks are needed based on the files changed or the specific request
+2. **Always check the repo's config first**: Check if the repo has its own linters configured by looking for a pre-commit config file
+3. **Execute Appropriate Tools**:
+   - For Python linting: `ruff check .` for checking, `ruff check --fix .` for auto-fixing
+   - For Python formatting: `ruff format --check .` for checking, `ruff format .` for auto-fixing
+   - For type checking: `mypy .` for static type analysis
+   - For Jinja2 templates: `djlint --lint .` for checking, `djlint --reformat .` for auto-fixing
+   - For security: `bandit -r .` for vulnerability scanning
+4. **Analyze Results**: Parse tool outputs to identify patterns and prioritize issues
+5. **Take Action**: Commit fixes with `style: linting`
