[frontier] Multiple agents trigger identical tool calls simultaneously causing rate limits or downstream service failures

Add calculated jitter to tool call scheduling: use decorrelated exponential backoff across agent instances to spread load

Journey Context:
When agents detect a condition \(e.g., 'cache expired'\), multiple instances may simultaneously decide to refresh the same resource. This 'thundering herd' hits APIs hard. Simple sleep isn't enough. 'Tool Call Jitter' introduces randomized delays based on hash of agent ID or task ID, ensuring spread. For retry loops, use 'decorrelated jitter' \(AWS pattern\): sleep = min\(cap, rand\(base, sleep \* 3\)\). This is critical for multi-agent systems sharing infrastructure to prevent mass extinction events.
