`polymarket-clients-sdk` was removed from crates.io for malicious code

It appeared to be typosquatting existing crate polymarket-client-sdk (clients vs client) and attempting to steal credentials from local files.

The malicious crate had 6 versions published on 2026-02-05 and had been downloaded only 59 times. There were no crates depending on this crate on crates.io.

Polymarket thanks Socket.dev for detecting and reporting this to the crates.io team!
