src/viz/funnel_tab.rs
//! 🗂 **Funnel** tab — the idea→plan DAG (DAG 2) as an interactive
//! [`egui_snarl`] node graph.
//!
//! A plan is literally a DAG: nodes carrying a `kind` + `status`, wired by
//! dependency edges. We lay it out **topologically** (longest-path layering →
//! one column per rank, deps strictly left of dependents) and render it with
//! egui-snarl, so it pans/zooms/drags like a modern node editor while the
//! topology stays readable. Node + pin tint encode lifecycle
//! (pending/ready/in-progress/done/blocked/failed).
//!
//! Data is read **embedded** (open the funnel `Store` locally) or **remote**
//! (the `Funnel.Show` gRPC RPC), collapsing into [`FunnelView`] — exactly the
//! local-or-remote split the call-graph + warehouse tabs use. Writing the
//! funnel stays where it belongs: the `nornir funnel` CLI and the `funnel_*`
//! MCP tools. This tab is the read/observe surface.
