[Execution] Detect transient liquidity manipulation around simulation and settlement

[fishonamos]

Problem

An attacker can distort shallow pools during simulation or just before execution, causing unsafe routes despite nominal slippage limits.

Required work

Add liquidity-depth, historical deviation, multi-source, and pre-settlement checks with configurable circuit breakers.

Acceptance criteria

• Manipulation signals are recorded with the quote.
• High-risk routes require stricter policy or rejection.
• Checks cannot be bypassed by splitting a route.
• Adversarial tests model flash liquidity and reserve spoofing.
