run sync tools with threads in call_func_async

[KeremTurgutlu]

call_func_async previously called sync functions directly on the event loop, blocking it and preventing asyncio.gather from running multiple tool calls concurrently. Now sync functions are wrapped in asyncio.to_thread, enabling true parallel execution. Async functions are detected via inspect.iscoroutinefunction and awaited directly as before.

Fixes #72

Nice!

FYI @KeremTurgutlu it's best not to have both an issue and a PR, especially if they both have a label, otherwise we end up with both appearing in the changelog. If you want to add an issue to help track things, just leave it unlabelled.
