   Title: Gemini API integration fails with Invalid function name error when .voidrules is empty

Body:

Hi Void team 👋

I’m running into an issue when using Void IDE with my Google Gemini API key.

Whenever I try to post a question, I get this error:

ClientError: got status: 400 Bad Request.
{"error":{"message":"{
"error": {
"code": 400,
"message": "* GenerateContentRequest.tools[0].function_declarations[15].name: Invalid function name. Must start with a letter or an underscore. Must be alphameric (a-z, A-Z, 0-9), underscores (_), dots (.) or dashes (-), with a maximum length of 64.

• GenerateContentRequest.tools[0].function_declarations[16].name: Invalid function name. Must start with a letter or an underscore. Must be alphameric (a-z, A-Z, 0-9), underscores (_), dots (.) or dashes (-), with a maximum length of 64.\n",
  "status": "INVALID_ARGUMENT"
  }
  }"}

Key details:

My .voidrules file is empty (so I’m not defining any custom tools/rules).

The error still occurs, so it looks like the invalid function names are being generated internally by Void when constructing the Gemini GenerateContentRequest.

The API key itself is valid (tested directly with Gemini outside of Void).

Steps to reproduce:

Configure Void with a Gemini API key.

Ask any question (no .voidrules defined).

Receive 400 Bad Request with invalid function name error.

Expected behavior:

Requests should succeed, with no invalid function names being passed when .voidrules is empty.

Actual behavior:

Gemini rejects the request with INVALID_ARGUMENT due to two invalid function names in function_declarations.

✅ Can you confirm if this is a known issue in the current Gemini integration?

Thanks for the awesome work on Void 🙏
