/**
 * Tree renderer for `cleo tree` / `cleo deps tree` / `cleo orchestrate`.
 *
 * Handles four data shapes returned by the `deps`/`tree` dispatcher:
 * - `data.waves`     — enriched wave array from `orchestrate.waves`
 * - `data.tree`      — recursive `FlatTreeNode[]` from `tasks.tree`
 * - `data.rendered`  — pre-formatted text/mermaid string from `tasks.deps.tree`
 * - `data.tasks`     — flat `Task[]` fallback
 *
 * When `data.waves` is present, delegates to {@link renderWaves}.
 * When `data.rendered` is a string, emits it as-is — CORE has already produced
 * the canonical text/mermaid output; this renderer is a thin wrapper that just
 * prints it.
 *
 * Migrated from `packages/cleo/src/cli/renderers/system.ts` (T10131 — B6).
 *
