## Description

Retry-go is a utility library for Go that automates the re-execution of failing code blocks and operations until they succeed or exhaust configured attempt limits. It provides mechanisms for handling transient failures, capturing both computed results and final errors from repeatedly executed functions.

The library supports configurable retry timing through fixed intervals, exponential backoff strategies, and randomized jitter to control recovery speed and prevent overwhelming recovering services. It also includes error filtering rules that trigger retries on specific error conditions while halting execution immediately for unrecoverable failures, alongside lifecycle management features such as timeouts, cancellation signals, attempt callbacks, and reusable persistent policies.
