UX issues with Gemini CLI Module

[bpmct]

Extracted from #259

• The first snippet doesn't include the required variable for Gemini API key or instructions to get it
• AI Prompt is built-in to the module in this one, but not Claude Code leaving an odd troubleshooting UX
• Gemini icon doesn't work
  
• By default, Gemini CLI runs in the home directory and requires explicit approvals. It should be automatic.
• Link to docs (https://ai.google.dev/gemini-api/docs/cli) 404s from the module README
• I tried to configure yolo mode with gemini_settings_json = jsonencode({"geminicodeassist.agentYoloMode": "true"}) but didn't seem to work
• I had to manually confirm that I wanted to use the API key to auth with AgentAPI versus it kicking off
