GHSA-mh23-rw7f-v5pq: `time-sync` was removed from crates.io due to malicious code

Severity: Critical

CVSS Score: 10

The `time-sync` crate attempted to exfiltrate `.env` files to a server that was in turn impersonating the legitimate `timeapi.io` service. This the same attack that we've seen three times in the last few days. The malicious crate had 1 version published on 2026-03-04 approximately 50 minutes before removal and had no evidence of actual downloads. There were no crates depending on this crate on crates.io.
