refactor: Update CLI commands to use new unified entry points

Updated all command examples in CLI scripts from old pattern:
  python3 cli/<script>.py → skill-seekers <command>

Changes:
- doc_scraper.py → skill-seekers scrape
- github_scraper.py → skill-seekers github
- pdf_scraper.py → skill-seekers pdf
- unified_scraper.py → skill-seekers unified
- enhance_skill.py → skill-seekers enhance
- enhance_skill_local.py → skill-seekers enhance
- package_skill.py → skill-seekers package
- estimate_pages.py → skill-seekers estimate

This reflects the new modern Python packaging with proper entry
points. Users can now use clean commands instead of file paths.

Files updated: 10 CLI scripts
