QA: Agent Config Object — Mastra

Test Steps

• Navigate to /demos/agent-config
• Verify the ConfigCard is rendered with tone, expertise, responseLength controls
• Set tone = "playful", expertise = "beginner", responseLength = "short"
• Ask "Explain TCP"
• Verify the response is short and playful-beginner tone

Expected Results

• Config forwarded via useAgentContext; agent adapts

Mastra-specific note

The LangGraph reference uses runtime properties passed to a dedicated route. Mastra's Memory primitive doesn't forward these in the same way, so this port uses useAgentContext — functionally equivalent from the user's perspective but a different wiring pattern.
