[BUG] System prompt doesn't seem to apply

[MrCsabaToth]

Describe the bug:
The system prompt for both the commander and the agents describe who they are. Therefore for a question "who are you" the chat should not respond with the generic Gemma3n reply.

To Reproduce:

1. Start the app.
2. Select Nearby Chat tile
3. Pick either commander or agent role
4. I assume you already have a downloaded model so click Try
5. Ask "who are you" or "what's your role"
6. Observe the response

Expected behavior:
We expect a summary of the identity description in the system prompt. Instead a generic cookie cutter Gemma3n response is regurgitated.

Additional context:
This comes with both the local LLM chat, or if it is sent over to the agents to respond.
