Retry policy configuration

Fields

max_retries: u32

Maximum number of retries

strategy: RetryStrategy

Retry strategy

retry_on: Vec<String>

Exceptions/error patterns to retry on (empty means retry all)

dont_retry_on: Vec<String>

Exceptions/error patterns to not retry on

retry_on_timeout: bool

Whether to retry on timeout errors

preserve_on_failure: bool

Whether to preserve the original task on failure (don’t move to DLQ)
