anthropic: handle top-level system param; bump version#21
Merged
Conversation
Add support for a top-level `system` parameter for the Anthropic provider: include `system?: string` in AnthropicCreateArgs, convert a top-level `system` into a system message when building LLMRequest, and extract a system message back to the top-level `system` when converting a request to args. Filter out system messages from messagesToAnthropicInput and ensure extractParams ignores the `system` field. Also bump package version to 0.1.5-beta in package.json and package-lock.json.
