update the Symbolica Typst plugin to upstream main User request: "yeah lets update to main. Also what is the license situation for symbolica keys? currently?" Approved follow-up: "Approve these protocol test updates" for /tmp/plugin-main-update/test-protocol.patch. Pin upstream main at 18e0491628f9eac5c788659cabfcdb7575f6986d, migrate to symbolica-typst-atom-payload and the matching Typst protocol, and validate native, Python and WebAssembly interoperability locally.
