feat(monitoring): add real-time web dashboard for monitoring benchmark progress

[JoeXic]

Describe this PR

Add real-time web monitoring dashboard for GAIA validation benchmark with progress tracking and visualization capabilities.

What changed?

• Added run_gaia_with_monitor.py to run GAIA benchmark with integrated web monitoring
• Added utils/progress_check/gaia_web_monitor.py - web dashboard for real-time progress tracking
• Added utils/progress_check/generate_gaia_report.py - report generation utility
• Updated main.py to support the new monitoring command
• Web dashboard accessible at http://localhost:8080 during benchmark execution

Why?

Running long benchmarks like GAIA validation requires hours, and users need a way to:

• Monitor real-time progress without constantly checking logs
• Visualize task completion status
• Track performance metrics during execution
• Generate comprehensive reports after completion

Describe this PR

Refactor monitoring system from GAIA-specific to generic benchmark monitoring, supporting GAIA, FutureX, xbench, and FinSearchComp benchmarks with real-time web dashboards.

What changed?

Core Changes

• Replaced run_gaia_with_monitor.py → run_benchmark_with_monitor.py (generic benchmark runner)
• Replaced utils/progress_check/gaia_web_monitor.py → utils/progress_check/benchmark_monitor.py (generic monitor)
• Replaced utils/progress_check/generate_gaia_report.py → utils/progress_check/generate_benchmark_report.py (generic report generator)
• Updated main.py to use the new generic monitoring system
• Updated utils/progress_check/check_finsearchcomp_progress.py (fixed type annotation)

New Features

• Auto-detect benchmark type from log folder path
• Support benchmark-specific metrics:
  • GAIA/FinSearchComp: Correctness evaluation (accuracy)
  • FutureX/xbench: Prediction tracking (prediction rate)
  • FinSearchComp: Task type breakdown (T1/T2/T3) and regional analysis
• Extract attempt number from log filename for accurate report generation
• Suppress verbose HTTP logs in web dashboard
• Automatic port conflict resolution

Documentation

• Added monitor_guide.md - Web monitoring dashboard guide

Why?

Running long benchmarks (GAIA, FutureX, xbench, FinSearchComp) requires hours, and users need a way to:

• Monitor real-time progress without constantly checking logs
• Visualize task completion status with benchmark-specific metrics
• Track performance metrics during execution (accuracy for GAIA, prediction rate for FutureX/xbench)
• Generate comprehensive reports after completion
• Use a unified monitoring system across all benchmarks instead of benchmark-specific solutions
