PR Summary

Medium Risk
Major scc upgrade plus lockfile churn pulls in new transitive crates and changes low-level deps like socket2 and windows-sys, which could affect networking/concurrency behavior and platform builds.

Overview
Updates the workspace dependency on scc from 2.4.0 to 3.0.0.

Regenerates Cargo.lock for the new resolver, introducing new transitive crates (e.g., saa) and shifting several dependency versions (notably socket2 and windows-sys).
