fix(install): download from npm registry instead of GitHub releases

Updated install.sh to fetch tarballs from npm registry instead of
GitHub release assets. This allows the installer to work with the
published @socketbin packages.

Changes:
- get_latest_version() now queries npm registry API
- Download URL now points to npm registry tarball
- Removes dependency on GitHub releases
