Exponential back-off strategy for retry loops.

Backoff interface — Next() time.Duration, Current() time.Duration, Wait(), Reset().
Exponential struct (implements Backoff); NewExponential(initialInterval, multiplier, maxInterval, resetAfter time.Duration) Exponential.
const DefaultInitialInterval = 500ms, DefaultMultiplier = 1.5, DefaultMaxInterval = 60s.

A zero-value Exponential is usable: missing/zero constructor args are lazily replaced with the package defaults on first Next()/Current() call.
resetAfter (4th constructor arg): if the time since the last Next() call exceeds it, the interval auto-resets to the initial value; pass 0 to disable auto-reset.
Not concurrency-safe — use one instance per goroutine, or add your own locking. No dependency on other repo packages; used internally by yatgclient for reconnect backoff.
Fx: BackoffModule (fx.go) provides a Backoff from a supplied ExponentialParams.
