//! `kigi import-kimi` — one-time, read-only import of the official kimi-cli
//! configuration (`~/.kimi`), PRD F7.
//!
//! Reads `~/.kimi/config.toml` + `~/.kimi/mcp.json` without modifying them
//! and merges MCP servers, custom model providers, and the default-model
//! preference into `~/.kigi/config.toml`. Existing kigi entries are never
//! overwritten. A marker file under the kigi home makes the import one-time.
