/**
 * canonical-sort-v1 — Deterministic JSON serialisation for commitments.
 *
 * Produces a canonical byte string from arbitrary JSON so that the same logical
 * data always yields the same commitment, regardless of key ordering or number
 * formatting in the source response.
 *
 * Rules (subset of RFC 8785 / JCS):
 *  1. Object keys sorted by Unicode code point (UTF-16 code unit comparison).
 *  2. Deep objects: recursively sorted (NOT flattened).
 *  3. Arrays: order preserved (NOT sorted); elements recursively canonicalised.
 *  4. Numbers: shortest round-trip representation (`String(n)`); `-0` → `"0"`.
 *  5. Strings: standard JSON escaping.
 *  6. No whitespace.
