* Fix Anthropic API compatibility issues in chat completions

solves two important compatibility issues between the LM Eval Harness and Anthropic's API:

1) The type field issue - Anthropic's Messages API doesn't accept the type field that other APIs might expect, that was previously included
2) The stop sequences issue - Anthropic requires stop sequences to contain non-whitespace characters

tested with most recent models from anthopic; claude-sonnet-4-0, claude-opus-4-0, resolved my local api errors

* pacufy pre-commit

* add type
