 *   1. When `opts.format === 'json'`, return `''` immediately — the JSON
 *      path is the caller's responsibility.
 *   2. Look up a renderer registered for exactly `(command, envelope.kind)`.
 *      If present, delegate.
 *   3. Otherwise delegate to {@link renderFallback}, which handles every
 *      envelope kind via inline string concatenation + B4 helpers.
 *
 * @typeParam T — envelope payload shape.
 * @param envelope The typed envelope produced by an operation.
 * @param command  The command that produced the envelope (e.g. `'tasks.list'`).
 * @param opts     Per-call render options. Defaults to an empty object.
 * @returns The string to write to stdout. Empty string suppresses output.
