Lark Shared

Handles the foundational setup and authentication flow for Lark/Feishu CLI operations. Walks you through initial app configuration with `lark-cli config init`, manages the two-layer permission system (backend scopes plus user authorization), and crucially helps you pick the right identity with `--as user` versus `--as bot`. The bot identity can't see user calendars or documents, which trips people up constantly. When you hit permission errors, it parses the response to guide you through either backend scope configuration or the proper `auth login` command. Also catches version update notices and reminds you to restart your AI agent after CLI updates.
