feishu-cli-toolkit 是做什么的？
Feishu lightweight toolkit and triage entry point. Only use when no more specialized skill is available, mainly covering basic spreadsheets, calendars/events, tasks/task lists, basic files/assets/comments, knowledge base, user and department queries, and approval queries. Document read/write/import/export, cloud drive enhancements, multidimensional tables, whiteboards, messages/chats, email, search, permissions, OAuth, video conferencing/notes should preferentially use the corresponding feishu-cli-* dedicated skills. Sheet filter-view/dropdown should use feishu-cli-sheet first; calendar suggestion/room-find/rsvp should use feishu-cli-calendar first.
