refactor(version): extract version formatting helpers and improve build info display

Extract formatVersion() and formatBuildInfo() helper functions to reduce code duplication between printVersion() and statusCmd(). Update git commit default value to "dev" in Makefile for consistency with version handling. Update documentation for QQ and DingTalk chat integration in Japanese README.
