PROTOBUS: gRPC over vscode message passing (RooCodeInc#2830)

* initial protobuf setup & rough domains

* delete old protos for now

* phase 1

* initial working demo

* simplify call a bit more

* remomve some comments

* use common.proto

* remove redundant browser-service layer, clean up naming

* delete mcp proto for now

* better client layout & easier service imports

* a reflection-based way to create grpc services automatically

* better code layout for grpc implementations

* switch to auto-generating the method registration via bash

* hook protobufs into package.json scripts

* make service implementations more generic

* warn user that they must install protoc deps

* delete old message passing for getBrowserConnectionInfo

* format fix

* format fix

* rewrite build-protos in node & update package.json

* don't protoc during package

* change how imports work based on feedback

* package lock seems necessary now
