feat(backend): enhance instance management for editor support

- Sync instance.version_id after start_game, install_fabric, install_forge
- Add jvm_args_override and memory_override to Instance struct
- Add file management commands: list_instance_directory, delete_instance_file, open_file_explorer
- Support per-instance settings overrides (Java args, memory)
