Fix CLI path references in documentation

Following PR #145 which fixed README.md, this commit corrects all
remaining documentation files to use the correct cli/ directory prefix
for Python scripts.

Changes:
- QUICKSTART.md: Fixed 21 occurrences (doc_scraper.py, enhance_skill_local.py, package_skill.py)
- docs/UPLOAD_GUIDE.md: Fixed 10 occurrences (doc_scraper.py, enhance_skill_local.py, package_skill.py)
- docs/ENHANCEMENT.md: Fixed 9 occurrences (doc_scraper.py, enhance_skill.py, enhance_skill_local.py)

All commands now correctly reference:
- python3 cli/doc_scraper.py (not python3 doc_scraper.py)
- python3 cli/enhance_skill.py (not python3 enhance_skill.py)
- python3 cli/enhance_skill_local.py (not python3 enhance_skill_local.py)
- python3 cli/package_skill.py (not python3 package_skill.py)
- python3 cli/estimate_pages.py (not python3 estimate_pages.py)

This ensures all documentation examples work correctly when run from
the repository root directory.
