malkhut(docs): README updated for three-dimensional order type model

Updated README to reflect Fable's corrections:
- OrderType/TimeInForce/Instructions as three orthogonal dimensions
- POST_ONLY/IOC/FOK correctly described as non-types
- BingX trailing_stop -> TRAILING_STOP_MARKET
- Three mapping tables (order type, TIF, instructions)
- Integration status updated

 ### Order Type Standardization (Multi-Exchange, FIX/CCXT-Aligned)
 
-Normalized order type taxonomy based on **FIX Protocol Tag 40 (OrdType)** as the
+Three **orthogonal dimensions** (not one flat enum), each mapped independently:
-universal reference, with **CCXT** de facto crypto standard for practical interop.
-Neither MiFID II nor MiCA defines a standalone order type taxonomy — both defer to FIX.

-#### Cross-Exchange Mapping (BingX ↔ Binance ↔ Bybit)
+**Dimension 3 — Instructions (FIX Tag 18 ExecInst):** behavioral modifiers
+`POST_ONLY`, `REDUCE_ONLY`, `HIDDEN`, `ICEBERG`
+
+> CRITICAL: `POST_ONLY` is an instruction on a `LIMIT` order, not a standalone type.
+> `IOC`/`FOK` are TimeInForce values applied to a `LIMIT` order, not order types.
+> This aligns with FIX Protocol: Tag 40 (OrdType), Tag 59 (TimeInForce), Tag 18 (ExecInst).

-#### Integration Status
-
-- `state.py` OrderType: **17 values** (5-layer taxonomy, backward compatible)
-- `order_types.py`: **Standalone standardized taxonomy** with exchange mapping tables
-- `ExchangeProfile.available_order_types`: per-venue list of supported normalized types
-- `action_menu.py`: uses `OrderType.MARKET`, `OrderType.LIMIT`, `OrderType.POST_ONLY`
-- CWM transition: passes `action.order_type` to venue adapter
-- Agent/adversary code: check `is_type_available(type, exchange)` before placing
