fix: add local_mode config fields to Mac/Linux, fix Android companion object

- Mac/Linux config.rs: add local_mode_key and local_mode_port fields
  (required for local_server.rs to compile)
- Android: merge duplicate companion object into single block
  (Kotlin only allows one companion object per class)
