Add option to "Always inject hidden prompt and character" «Help me set up the feature please, only with it I can use the application.»

The extension currently injects the hidden system prompt and RP character only once per session (on the first message). For roleplay and consistent formatting, I need them to be injected into every single message, not just the first one.

Please add a setting to choose the prompt injection frequency:

Always (every message)

Every N messages (e.g., every 1st, 2nd, 3rd…)

Only on first message (current behavior)

If a frequency selector is too complex, at least a toggle "Always inject prompt" would be enough — that's the minimum to make the extension usable for me.

P.S. If possible, I would be satisfied with at least a way to manually modify the current version of the extension, so the prompt is injected on every message. I don't necessarily need to wait for a new release – any instruction or pointer on what to change in the code would be enough.
