⚡ Concurrent File Upload Optimization

[rmedranollamas]

⚡ What:
Optimized ResearchAgent.UploadFiles in internal/agent/files.go to process file uploads concurrently using Go's golang.org/x/sync/errgroup with errgroup.WithContext.

🎯 Why:
Previously, UploadFiles executed file uploads synchronously in a loop. Uploading multiple files resulted in blocking sequential I/O overhead.

📊 Measured Improvement:
Benchmark testing with 5 files and simulated 10ms I/O latency:

• Sequential baseline: ~51.7 ms / op
• Concurrent optimization: ~10.4 ms / op
• Improvement: ~5x speedup (80% reduction in execution time for multi-file uploads) while preserving URI output ordering and cancellation behavior.
