⚡ Bolt: Concurrent Execution of Tool Calls in Retrieval Pipeline

[ishaanxgupta]

💡 What: Replaced the sequential for loop executing tools (_execute_tool) with an asyncio.gather call mapped over an inner _process_tool_call(tc) async method in src/pipelines/retrieval.py's run method.
🎯 Why: To drastically reduce latency bottlenecks. Sequential execution meant overall wait time scaled linearly with the number of tools requested. Running them concurrently bounds time spent to the longest single tool request.
📊 Measured Improvement: Baseline measurements taking ~1.5s for 3 tasks with simulated 0.5s delays dropped to ~0.5s, confirming a ~3x performance improvement for 3 concurrent tool calls.
