fix: cap API retry exponential backoff at 10 minutes

Prevents excessive retry delays when auto-retry is enabled. Previously,
the exponential backoff could grow to hours (e.g., 7168s after 11 retries
with 7s base delay), causing "all night prompts" to get stuck waiting.
Now capped at 600 seconds (10 minutes) maximum.

Fixes #2724
