[OMEGA-244] Change OpenRouter prompt to the default we use for not so chatty and spammy (it talks too much now)

[jazzbox35]

Description

The OpenRouter option using GLM overwhelms the user with unnecessary questions. Switch to using the restrained prompt.

How Has This Been Tested?

I tested this with a few questions and it worked.

Thanks Mike, looks good to me. Prompt is equal to the prompt_ASICloud.txt but technically the only way to add it is to copy it.

I think we need to test it accurately. So I will raise the task and link it with PR.

Tested #244 on live GLM via OpenRouter and the chattiness is gone. Without the prompt GLM answered one request with 5 messages (1 answer plus 4 idle "ready/awaiting"), with the prompt just the answer. I also checked that the anti-spam lines actually reach the model in its prompt, not just went by the reply count.

The prompt is picked by provider name, so it covers provider=OpenRouter, the GLM case in the title. Good to merge for that.

One gap outside this task: when we build with provider=MiniMaxM3, that runs the minimax model through OpenRouter, and it has no prompt file of its own, so it falls back to the default and still spams. The same minimax model over ASICloud is already fine, so covering MiniMaxM3 is just one more copy of that file, better as its own ticket.

This is fixed in #222 where user is able to specify provider and model separately. MiniMaxM3 provider is removed from the list of providers.
