Integrate web search for real-time / current event answers

Problem

LLMs have a training cutoff and cannot answer questions about current events, live scores, today's weather, recent news, etc. This is a significant gap for a general-purpose voice assistant.

Proposed Solution

• Integrate a free-tier search API (e.g., Brave Search API or SerpAPI)
• Before calling the LLM, detect if the query likely needs real-time data (keywords: "today", "now", "latest", "current", "news", etc.)
• Fetch top search results and inject them as context into the LLM prompt (basic RAG)

Acceptance Criteria

• Queries about current events return up-to-date information
• Search is only triggered when the query appears to require real-time data
• Latency impact of the search step is measured and acceptable
