Module backoff 

Exponential backoff with jitter for supervisor restart strategies.

delay = min(cap, base * 2^attempt) + jitter

Where jitter is a random value in [0, base * 2^attempt) to prevent thundering-herd scenarios when multiple services restart simultaneously after a shared outage.

Features

• Exponential growth with configurable base and cap
• Full jitter to desynchronize concurrent restarts
• Cooldown reset: if a service runs successfully for a configurable period, the attempt counter resets to zero so occasional rare failures don’t accumulate toward a long backoff
• Circuit breaker: if a service fails N times within a window T, the supervisor terminates the service rather than retrying forever

Structs
