node 24.22 broke sass sync compile, Compiler caused error: Invalid protobuf

Error: Compiler caused error: Invalid protobuf: Error: illegal tag: field no 13 wire type 6.

only the sync compile() in sass-embedded, only on node 24.22, only when the css output is BIG. compileAsync is fine and 24.21 is fine. fun

The fix is in sync-child-process 1.1.1, which is on npm now. sass-embedded allows ^1.0.2 so no new sass release is needed, just refresh the lockfile so it pulls 1.1.1.
