/**
 * Adapter that wraps a legacy `(data, quiet) => string` renderer into the B5
 * {@link Renderer} signature so it can be registered with
 * {@link registerRenderer}.
 *
 * The legacy renderers migrated by T10131 (B6) and its sibling B7/B8 PRs all
 * have the historical `(data: Record<string, unknown>, quiet: boolean) =>
 * string` shape. The B5 registry expects `(envelope, opts) => string`. This
 * adapter bridges the gap so the registry can be populated incrementally
 * without forcing every consumer to migrate to {@link RenderableEnvelope}
 * payloads at once.
 *
 * **Mapping rules**:
 *   - The envelope's `data` payload is unwrapped and forwarded as the legacy
 *     `data` argument when the envelope kind is `'generic'`, `'single'`, or
 *     any other unwrappable variant. For collection variants (`tree`,
 *     `table`, `list`, `grouped-list`), the entire `data` object is passed
 *     through so the legacy renderer can read whatever keys it expects.
 *   - The quiet flag is derived from {@link RenderOptions} — `verbose === false`
 *     OR an explicit `(opts as { quiet?: boolean }).quiet === true` maps to
 *     legacy `quiet=true`. The default is `quiet=false` (full output).
 *
