feat: Update interactive CLI with Docker tools and deprecated section

- Replace old deployment options with new Docker management tools
- Add Docker commands: start, stop, show status
- Add docker-compose.yml generation
- Add link checking tools (quick and full)
- Group deprecated options under separate section with visual separators
- Mark all old deploy system tools as deprecated
- Add clear warnings to use Docker workflow instead

Interactive menu now shows:
  1. New Docker & Link Checking tools (primary)
  2. Visual separator with 'DEPRECATED OPTIONS' label
  3. Old deployment tools (export, deploy, backup, cleanup)
  4. Exit option

All deprecated functions still work but show warnings in output.
