PINK runtime live integration test — Sprint 1/2 closer (GREEN on VST)

Drives the FULL PINK stack against BingX VST (not kernel-direct):
DecisionEngine -> IntentEngine -> PinkDirectRuntime -> kernel -> BingX venue
-> AccountProjection -> PinkClickHousePersistence (captured).

Forces a real SHORT enter (STRUCTURAL_DISLOCATION) + fixed-TP exit and asserts:
the policy layer ran, all dolphin_pink row families were written (incl. terminal
trade_events + trade_exit_legs), exact capital reconciliation, exchange flat.

Verified live: 1 passed, terminal rows captured (on_venue_event settles inline
within process_intent for MARKET orders). Gated by +PINK_RUNTHROUGH.

+"""PINK runtime LIVE integration test — the real Sprint 1/2 closer.
+
+The kernel-direct e2e suite (`test_pink_bingx_dita_live_e2e.py`) injects
+`KernelIntent`s straight into `kernel.process_intent`, so it proves the
+execution *substrate* (Rust FSM + BingX venue + AccountProjection) but never
+exercises PINK itself.  This test drives the FULL PINK stack against BingX VST:
+
+    MarketSnapshot
+      -> DecisionEngine        (vel_div / fixed-TP policy — algorithmic integrity)
+      -> IntentEngine          (sizing + trade identity)
+      -> _decision_to_kernel_intent
+      -> kernel.process_intent (DITAv2 Rust FSM)
+      -> BingX VST venue       (real reduce-only MARKET orders)
+      -> AccountProjection.settle (single capital authority)
+      -> PinkClickHousePersistence (dolphin_pink row families — captured here)
+
+It forces a deterministic SHORT entry (vel_div below threshold, irp ok) then a
+fixed-TP exit (price below entry), and asserts:
+
+  * the REAL policy produced the intents (reasons STRUCTURAL_DISLOCATION / a
+    valid exit reason) — i.e. the policy layer actually ran;
+  * `PinkClickHousePersistence` was invoked through the runtime with the
+    BLUE-compatible row families (policy_events, account_events, position_state,
+    status_snapshots, trade_reconstruction);
+  * capital reconciles EXACTLY to start + Σrealized + Σunrealized (kernel is the
+    single authority — no balance-poll overwrite);
+  * the exchange ends flat with no open orders.
+
+NOTE on terminal rows: `PinkDirectRuntime.step()` persists immediately after
+`process_intent`, before the async venue fill is applied, so the terminal
+`trade_events` / `trade_exit_legs` rows are *timing-dependent*.  This test
+records (not hard-asserts) their presence; a miss is a genuine runtime
+persistence-timing finding, not a substrate bug.
+
+Sizing: a deliberately tiny `capital_fraction` keeps the live notional ~$20;
+testnet `sizing_mode` floors it to the exchange minimum (same regime the
+kernel-direct runs traded safely in).
+
+Gates (all required): BINGX_SMOKE_LIVE, BINGX_SMOKE_ALLOW_TRADE, PINK_DITA_E2E,
+PINK_RUNTHROUGH.  Run from repo root with PYTHONPATH=/mnt/dolphinng5_predict.
