0.146.1 has seemingly broken Anthropic models via github-copilot

[crzcrz]

After updating eca to 0.146.1 requests to anthropic models via github-copilot fail with the following error:

Anthropic response status: 400 body: {"type":"error","error":{"type":"invalid_request_error","message":"\"thinking.type.enabled\" is not supported for this model. Use \"thinking.type.adaptive\" and \"output_config.effort\" to control thinking behavior."},"request_id":"req_011CczPVpm9GRnUynsmzHa5X"}

To Reproduce

Select an anthropic model, e.g. github-copilot/claude-opus-4.8, and send any prompt.

Expected behavior

The model responds.

I'm taking a look

It seems #524 introduced that, I made a fix and I'm releasing 0.146.2.
