fix(retry): limit max retry attempts to 10 and reduce max delay to 5 minutes

- Add RETRY_MAX_ATTEMPTS = 10 to prevent infinite retry loops
- Reduce RETRY_MAX_DELAY from 24.8 days to 5 minutes (300_000ms)
- Check attempt count in schedule step to stop after max attempts

Previously, a session could retry 113 times over 56 minutes. Now it will
stop after 10 attempts (max ~4.5 minutes total retry time).
