[idea] Publish to pypi and npm

[collinanderson]

idea / problem

what do you want to do, or what feels awkward today?

I want to uvx herdr / npx herdr and/or I want to use cooldowns to control how long before I get updates. and/or I want to avoid curl | bash installs.

requested change

publish to pypi and npm.

why you want this

• gives more exposure to herdr, makes it easier or more natural to install for some people.
• allows people to easily try it out with npx / uvx, without needing to install/uninstall
• allows people to use their already configured uv/npm cooldowns.
• gives people who avoid curl | bash an alternative that still auto-updates.
