…_decode Some providers (e.g. DeepSeek) may include raw control characters (0x00-0x1F, 0x7F) in streamed tool call argument JSON. These bytes are invalid per RFC 8259 and cause json_decode to throw a JsonException with "Control character error, possibly incorrectly encoded". Strip them before decoding. This mirrors the defensive approach already used in the OpenRouter streaming handler. Fixes prism-php#936

Summary
json_decodeinToolCall::arguments()JsonException: Control character error, possibly incorrectly encodedContext
Some providers (notably DeepSeek) occasionally include raw control characters in streamed tool call argument JSON. The OpenRouter handler already has defensive handling for malformed arguments — this adds similar protection at the
ToolCalllevel so all providers benefit.Fixes #936
