Pull Request Overview

This PR refactors the retry mechanism to use None for unlimited retry timeouts instead of using extremely large duration values. The change makes the API more explicit and semantically correct when dealing with operations that should retry indefinitely.

• Changed retry_timeout field from Duration to Option<Duration> in RetryOptions
• Updated retry logic to handle None as unlimited timeout and Some(duration) for bounded retries
• Replaced hardcoded year-long duration with None in live updater configuration
