Summary

This PR replaces the custom Failsafe-based retry strategy in RepositoryProvider with the standardized HxClient retry mechanism from lib-seqera, consolidating retry handling across the Nextflow codebase.

Key Changes

• Removed custom retry implementation (~70 lines of Failsafe-based retry logic)
• Integrated HxClient with HxConfig for sophisticated retry configuration
• Upgraded lib-httpx dependency from 1.0.0 to 2.0.0 to support HxConfig
• Maintained backward compatibility by preserving setRetryConfig() and isRetryable() method signatures
• Preserved all functionality including HTTP redirect handling for GitHub repository renames

Benefits

• Consistent retry strategy: All HTTP operations now use the same HxClient-based retry mechanism
• Reduced code complexity: Eliminated custom retry implementation in favor of centralized lib-seqera solution
• Better maintainability: Retry logic is now managed in a single location
• Enhanced configuration: More sophisticated retry policies through HxConfig

Implementation Details

The retry logic now uses HxConfig.builder() to configure:

• Retry conditions: Same exception types (SocketException, excluding UnresolvedAddressException)
• Retry status codes: HTTP 429, 500, 502, 503, 504
• Retry configuration: Uses existing RetryConfig for delays, max attempts, jitter, etc.

Test Coverage

• ✅ All repository provider tests pass (GitHub, GitLab, Bitbucket, etc.)
• ✅ HTTP redirect functionality verified (renamed repository test)
• ✅ nf-commons smoke test passes
• ✅ Maintains compatibility with existing retry behavior
