Bugfixes

• Backoff jitter - calculateBackoff() now applies jitter to prevent thundering herd when many jobs retry simultaneously. Exponential backoff uses ±50% jitter, fixed backoff uses ±20% jitter around the configured delay.
• Backoff max cap - Retry delays are now capped at 1 hour (DEFAULT_MAX_BACKOFF = 3,600,000ms) by default. Previously, attempt 20 with 1000ms base produced ~12 day delays. Configurable via BackoffConfig.maxDelay.
• Recovery backoff bypass - Startup recovery now uses calculateBackoff(job) instead of an inline exponential formula, correctly respecting backoffConfig (e.g., { type: 'fixed', delay: 5000 } was ignored during recovery).
