feat: add action-required.md to /create-feature command

Extends the /create-feature command to generate a third file that
extracts manual/human tasks into a dedicated checklist for better
visibility.

Changes:
- Add step 4 to create action-required.md with manual tasks
- Add template format with Before/During/After Implementation sections
- Add "no manual steps" template variant
- Update Next Steps to prioritize reviewing action-required.md
- Add note listing common manual task types (API keys, env vars, etc.)
- Bump create-agentic-app version to 1.1.27

Manual tasks (like account creation, environment variables, OAuth setup)
are now surfaced in a separate file so they're harder to miss during
feature implementation.
