malkhut(T5): risk gate + ASEx + IPC + storage + venue adapter

Browse Source 
Risk gate (risk/gate.py): hard invariants — leverage, self-trade, post-only.
ASEx integration (execution/asex_integration.py): validate-before-mutate,
single-writer, zero-lock state serialization.
IPC (ipc/): Zinc SHM (zinc_plane.py) + control plane (control_plane.py),
UVZINC01 seqlock framing.
ClickHouse storage (storage/ch_store.py): 5 tables, HTTP API.
BingX venue adapter (venue/bingx/adapter.py): wraps DITAv2, order tracking.

"""
ASEx integration for MALKHUT.
Builds ASEx's validate-before-mutate kernel into the core of MALKHUT:
- GuardedFulfilmentState: engine state mutations through ASEx
- GuardedRiskState: risk gate decisions through ASEx
- GuardedVenueState: venue adapter mutations through ASEx
- FulfilmentWorker: single-threaded ASExWorker for serialised engine
- ShardedFulfilmentWorker: per-symbol ShardedWorker for parallelism
- FulfilmentWatch: zero-overhead ASExWatch for hot-path ring buffer
The pattern: every mutable state object is an ASExGuardedState.
_mutate() calls _validate() first, then _apply() only if valid.
One worker thread per state. No locks. No races. No GC pressure.
