fix: Add crawl4ai console script entry point

[YuriNachos]

Summary

Fixes #1705

The crawl4ai console script was missing from [project.scripts] in pyproject.toml, causing pip to not generate the launcher executable on Windows when installing from the 0.7.8 wheel. Users could not use crawl4ai serve as documented.

List of files changed and why

• pyproject.toml - Added crawl4ai = "crawl4ai.cli:main" entry point to match the documented CLI usage

How Has This Been Tested?

The fix adds the missing console script entry point. After installing with this fix:

• crawl4ai serve will work as documented
• crawl4ai-setup, crawl4ai-doctor, etc. continue to work
• The crwl alias remains for backwards compatibility
