fix: handle async get_agent in load_agent_from_repository (#6608)

* fix: handle async get_agent in load_agent_from_repository

The enterprise PlusClient.get_agent() is async, but
load_agent_from_repository() calls it synchronously. When the enterprise
client is hooked in, client.get_agent() returns a coroutine instead of a
response, causing "'coroutine' object has no attribute 'status_code'".

This adds an inspect.isawaitable() check after the call: if the response
is a coroutine, it is properly awaited via asyncio.run() (or via a
thread-pool executor if an event loop is already running).
