//! Global flags shared by every builtin via `#[command(flatten)]`.
//!
//! `GlobalFlags` moved to the leaf `kaish-tool-api` crate so out-of-tree tools
//! flatten the same `--json` surface. Re-exported here so existing
//! `crate::tools::GlobalFlags` paths keep working. See `docs/clap-migration.md`.
