Resolve race condition during initial model load

[BachDao]

• The initial client establishes a connection with the server and initiates a model load operation.
• During the loading process, a second client connects and observes that the "model_loaded_external" flag remains false, prompting it to attempt loading the model again, leading to a race condition.

Great find!

I don't know why it's stuck at loading the model on Mac; I'm switching to Windows to test again.

The last write to the flag should be write_released instead of relaxed, will update when I get back to my laptop.

Anw, if your Windows running x86, it should be fine, otherwise problem in somewhere else.

Great, thank you! Let me know when you need me to test again.
