DEV: review proxy-agents necessity (loads of bloatware, unnecessary JS code bundled via WebPack, dynamic imports...)

[danielweck]

Example of dynamic import warning:

https://github.com/TooTallNate/proxy-agents/blob/b7e5f7ccce1a3ac5b339cc4c587974e8989cbc16/packages/negotiate/src/index.ts#L25-L33

There are also tons of bundle chunks generated into dist ... not sure all/any of them are necessary for our PROXY use case?

Fixed via weblate@d233f42

Removed PAC proxy type from ProxyAgent (preserve HTTP, HTTPS and Socks types) in order to eliminate QuickJS WASM and other massive bloat.

Note: Kerberos still not installed (PeerDependency) for ProxyAgent Negociate. This is a dynamic await import that will fail when used (but we don't set negotiate: true so it's fine)
