Add per-model provider + data-retention/prompt-training disclosure

Summary

It should be clear what's the prompt training and data retention policy on each model/provider. I don't care if Command Code doesn't train on my prompts and doesn't retain my data, that's pointless if the underlying provider could be doing that.. You're essentially saying today like "I don't use your data dude, just chill", but omitting that the underlying providers might be doing it.. Transparency is pretty important and that's why I cancelled my sub instead of upgrading it... Thought of upgrading but gave up after realizing that. It's not enough as well that you say that 98% of your models are zdr or no prompt training... It's only enough when you at least disclosure in your website the prompt training and retention policy for each model. And if possible, provide a way of disabling models whose provider might train on prompts...

Expected Behavior

Disclosure in your website the prompt training and retention policy for each model. And if possible, provide a way of disabling models whose provider might train on prompts...

Actual Behavior

Data Retention and Prompt Training policies at PROVIDER level are not disclosure. Privacy Policy is misleading as it talks about you, not the providers.

Steps to reproduce the issue

Try finding any disclosure on the prompt training or data retention policies per model... It doesn't even disclosure the providers per model..

首先檢視網站上的模型／提供者清單，以及 issue 中所參照的現有 Data Retention Policy。定義每個模型的提供者、提示詞訓練政策和保留政策應如何表示，並評估停用由提供者進行訓練的模型這項要求的選項。完成的標準是網站針對每個模型揭露這些政策，並在可行的情況下支援此 opt-out。
