⚡ Bolt: Cache SearchTool queries to prevent redundant agentic bottleneck

[thirdbase1]

💡 What: Implemented an in-memory Map cache inside the SearchTool.deep method to store and return results for previously executed search queries.
🎯 Why: Repeated agentic queries for the same context create an architectural bottleneck, wasting API calls and execution time during autonomous loops.
📊 Impact: Eliminates 100% of redundant search API calls/execution time for duplicate queries.
🔬 Measurement: Run tests before and after; any subsequent calls with the same query in the same session will return instantly (bypassing the mock search execution time).
