@cursoragent can we just call it sus?

[cursor]

Done! I've renamed the npm package from @superagent/sus to just sus. This makes it much simpler and more memorable:

Before:

npm install -g @superagent/sus

Now:

npm install -g sus

The changes include:

• Updated package.json to use the unscoped package name sus
• Updated README.md with the simpler installation commands
• Updated NPM_PUBLISHING.md to remove references to scoped packages and the --access public flag

All changes have been committed and pushed to the branch!

@cursoragent npm warn deprecated tar@6.2.1: Old versions of tar are not supported, and contain widely publicized security vulnerabilities, which have been fixed in the current version. Please update. Support for old versions may be purchased (at exorbitant rates) by contacting i@izs.me

[cursor]

Done! I've updated the tar dependency from ^6.2.0 to ^7.5.7 (the latest version) to address the security vulnerabilities mentioned in the deprecation warning. This ensures the package uses a secure, up-to-date version of tar for extracting the downloaded binaries.

The change has been committed and pushed to the branch.
