Type Alias RiskSignalQueue 

pub type RiskSignalQueue = Arc<Mutex<Vec<u8>>>;

Lock-free pending signal queue shared between executor layers and the agent loop.

Executors push u8 signal codes; begin_turn() drains the queue and calls TrajectorySentinel::record() for each entry. This avoids a reverse crate dependency between zeph-tools and zeph-core.
