//! `basemind code` — the CLI half of the `code` domain.
//!
//! Real clap subcommands rather than a `--mode` flag, so each lookup keeps its own `--help` and its
//! own argument validation; they map one-to-one onto the MCP `code` tool's [`CodeMode`] values,
//! which is what `tests/cli_parity.rs` asserts.
//!
//! Each handler leaves every field its mode does not use `None`: the helper rejects a field
//! belonging to another mode, so populating them blindly would fail the call.
