Opik adds reusable playground variants and tightens provider logging

Opik 2.2.128 through 2.2.131 are grouped here as one product update.

Reuse playground prompts

The playground can duplicate any prompt variant, add a blank variant, and load or save Text and Chat prompts. This is the main new workflow: users can preserve a baseline while preparing another prompt configuration rather than rebuilding every variant manually.

Provider handling changes

The follow-up releases keep provider header values and error bodies out of retry and error logs. They also adjust streaming header waits, transient-failure retries and handling of OpenAI error responses with additional fields.

Cost accounting changes include prompt-size tiers and one-hour cache writes. These are corrections to Opik’s accounting behavior, not new provider prices or a guarantee that a displayed estimate equals an invoice.

Other patches address optimization pagination and retained span payloads. The series is counted once because the later versions refine the same product workflow and provider integration, not because each patch is a separate launch.
