fix: add TTL to job records to prevent memory leak

Job records stored at {namespace}.jobs.{queue}.{pid} were accumulating
indefinitely because no TTL was set. This adds:

- TTL parameter to Connection interface set() and setArray() methods
- TTL support in Redis connection using setex()
- Configurable jobTtl property on Queue class (default: 24 hours)
- Cleanup of old job records after retry re-enqueue
