fix: multiple bugfixes

- Fix data race: use atomic.Bool for running in server.go
- Fix busy loop in timer.go: use time.After when idle
- Fix division by zero in print_replay
- Fix silently swallowed errors in proto_generator
- Fix suppressed error in native_encoder
- Delete unused registry_data_hunter
