fixed "fools" to "tools" typo in client.en.yml

Implement streaming tool call implementation for Anthropic and Open AI.

When calling:

llm.generate(..., partial_tool_calls: true) do ...
Partials may contain ToolCall instances with partial: true, These tool calls are partially populated with json partially parsed.

So for example when performing a search you may get:

ToolCall(..., {search: "hello" })
ToolCall(..., {search: "hello world" })

The library used to parse json is:

https://github.com/dgraham/json-stream

We use a fork cause we need access to the internal buffer.

This prepares internals to perform partial tool calls, but does not implement it yet.
