💡 What: Parallelized tool execution in the agent loop.
🎯 Why: Multiple tool calls (e.g., search for X, search for Y) were executed sequentially, causing unnecessary latency.
📊 Impact: Reduces total execution time to approximately the duration of the longest single tool call + overhead.
🔬 Measurement: Added internal/agent/loop_parallel_test.go which shows a drop from ~300ms to ~100ms for 3 concurrent 100ms tasks.

This change modifies the agent loop to execute multiple tool calls from a single LLM response concurrently. This significantly reduces latency when multiple tools are invoked (e.g., parallel web searches).

- Use `sync.WaitGroup` to execute tools in parallel.
- Collect results and preserve original order for deterministic conversation history.
- Ensure thread safety in `RuntimeMetrics` by holding the lock during file persistence to prevent race conditions and file corruption.
- Add regression test `internal/agent/loop_parallel_test.go`.
