Subject: [PATCH] Fix retryer exponential backoff using XOR instead of
 exponentiation

In Go, ^ is the XOR operator, not exponentiation. The expression 2^attempts
produced incorrect sleep durations (2s, 3s, 0s, 1s) instead of the intended
exponential backoff (1s, 2s, 4s, 8s). Use bit shift (1<<attempts) instead.
