v0.0.3

Full Changelog: v0.0.2...v0.0.3

EN:

• Improved default host startup behavior: when no config file is specified, the default config path is used; if no token is
  configured, one is generated automatically, saved to the config file.

zh_CN:

• 优化宿主端默认启动体验，未指定配置文件时会使用默认配置路径；若未配置 token，则自动生成并写入配置文件。
