⭐ feat: protobuf input messaging (#165)

Replace json protocol by protobuf
generate protobuf files with `bun buf generate` or just `buf generate`

- [x]  Implement all datatypes with proto files

- [x] Map to ts types or use the generated proto types directly with:
   - [x] web frontend
   - [x] relay
   - [x] runner

- [ ] final performance test (to be done when CI builds new images)
