/**
 *
 * Wraps `decomposeSlices` with a thin observability layer that records
 * total wall time, codegraph call count, confidence distribution, and
 * input/output byte counts. The result is attached to the
 * DecompositionResult envelope only when `peaks slice decompose --benchmark`
 * is passed.
 *
 * The benchmark does NOT mutate the algorithm's output; it is pure
 * measurement. Codegraph call counting is achieved by wrapping the
 * caller-provided `codegraphRunner`.
