build: streamline package discovery and bump to v0.4.244

- Replace explicit package listing with setuptools.find
- Include all crawl4ai.* packages automatically
- Use `packages = {find = {where = ["."], include = ["crawl4ai*"]}}` syntax
- Bump version to 0.4.244

This change simplifies package maintenance by automatically discovering
all subpackages under crawl4ai namespace instead of listing them manually.
