v0.20.1

v0.20.1

Patch release for the v0.20.x client latency-breaker configuration path.

Fixes

• Validate latency-breaker configuration during Service initialization:
  • thresholds and rolling window must be non-negative
  • recovery count must be non-negative
  • pass-through fraction must be in [0, 1]
• Normalize latency-breaker defaults in one path so direct client.Config usage and WithLatencyBreaker(...) behave consistently:
  • rolling window defaults to 1s
  • recovery count defaults to 3
  • pass-through fraction defaults to 0.01
• Wrap Service.init() errors with contextual %w errors while preserving the original cause.

Migration

No migration required for existing callers. The latency breaker remains disabled unless at least one latency threshold is configured.
