Get Neg RiskPolymarket-compat ``GET /neg-risk/{token_id}``.
Returns whether the market routes through Polymarket's
negative-risk contract — the REAL upstream flag, not a stub.
Resolution cascade:
1. Live CLOB ``/book`` payload's ``neg_risk`` bool (same source
``GET /v1/book`` serializes).
2. Last-known cached book (``orderbook:`` / ``clob:book:`` Redis
layers) when the live fetch blips.
3. Catalog classification off the market row's tags/category
(``_classify_neg_risk``) when no book is available at all.
4. ``404 {"error": "market not found"}`` — PM's live message
verbatim (probed 2026-06-11) — when the token resolves to no
known market.
Note: sim EXECUTION semantics don't change for neg-risk markets
we report the real flag so routing/branching code behaves like it
would against PM, but fills still settle per the standard binary
flow (documented divergence).
