RelPrim 0.9.0

Summary

RelPrim 0.9.0 adds provider-aware rate-limit recovery.

The release allows operations to use provider-supplied retry delays, fall back
to regular retry backoff when no hint is available, and avoid waits that exceed
an operation's configured maximum.

Added

• RateLimitPolicy
• RateLimitDecision
• RetryAfterExtractor
• rate_limit_policy()
• RetryAfterExtractionError
• AsyncOperation.with_rate_limit()
• @resilient(...) rate-limit configuration
• Provider retry-after delay handling
• Backoff fallback for missing retry hints
• Maximum acceptable wait enforcement
• Rate-limit report metadata
• Rate-limit structured events
• Rate-limit documentation and example

Behavior

Rate-limit handling integrates with the existing retry and fallback flow.

When the selected delay exceeds the configured maximum, RelPrim skips the retry
and proceeds to fallback or final failure.

Non-goals

This release does not add request throttling, a token bucket or a distributed
rate limiter.
