PR Summary

Medium Risk
Major-version upgrade of scc (concurrent container) plus lockfile re-resolution may introduce subtle behavioral or performance changes where scc is used, especially under concurrency and on Windows/network stacks.

Overview
Updates workspace dependency scc from 2.4.0 to 3.0.0.

Regenerates Cargo.lock accordingly, pulling in new transitive crates (e.g. saa) and shifting several dependency versions (notably sdd, socket2, windows-sys, and some proc-macro-related deps like darling/syn).
