//! Phase 23 — `nyx surface` subcommand.
//!
//! Walks the project tree, builds a [`SurfaceMap`] from the framework
//! probes (plus any persisted data-store / external-service /
//! dangerous-local nodes from a prior indexed scan) and renders the
//! map in the format requested by the user.
//!
//! Output formats:
//! * `text` — indented tree per entry-point, grouped by file
//! * `json` — canonical JSON (byte-identical to the SQLite payload)
//! * `dot` — graphviz source, ready to pipe through `dot -Tsvg`
//! * `svg` — graphviz source rendered via the local `dot` binary
//!
//! The command is read-only: it never persists to SQLite and never
//! modifies the project tree. It tries to load a previously persisted
//! map first; if none exists (no `nyx scan` ever ran, or the index was
//! cleaned) it falls back to building a fresh entry-point-only map by
//! running the framework probes against the on-disk source.
