fix(hub): ship checklist via cph_hub todo_write MCP tool

Native Claude TodoWrite is not registered in headless agent mode even with
--tools default. Add mcp__cph_hub__todo_write (always enabled), mirror the
TodoWrite schema, instruct multi-step runs to use it, and keep the Feishu
progress panel parsing both native and hub tool names.
