Add an awaitable prompt-loading API that mirrors `load_prompt()` while resolving
prompt metadata off the event loop:
```python
prompt = await braintrust.load_prompt_async(project="My Project", slug="my-prompt")
kwargs = prompt.build(name="Ada")
```
The API can be used with `asyncio.gather()` to load multiple prompts without
blocking the event loop:
```python
prompt_a, prompt_b = await asyncio.gather(
braintrust.load_prompt_async(project="My Project", slug="prompt-a"),
braintrust.load_prompt_async(project="My Project", slug="prompt-b"),
)
```
The async API reuses the existing sync `load_prompt()` implementation so cache
and fallback behavior stay consistent, and uses `asyncio.to_thread()` to avoid
blocking callers' event loops during the synchronous HTTP/cache lookup.
Tests cover eager metadata loading and parallel `load_prompt_async()` usage.
