SGLang CI Consecutive Failures Analyzer

Monitors GitHub Actions workflows for consecutive test failures and runner issues.
Detects failure streaks, tracks job health, identifies problematic runners, and generates alerts.

Features:
- Analyzes all jobs in PR Test workflow (excluding administrative jobs)
- Tracks consecutive failure streaks for each job
- Monitors runner health and failure rates
- Identifies whether failures are code-related or infrastructure-related
- Generates detailed reports with actionable recommendations

Usage:
    python ci_failures_analysis.py --token <GITHUB_TOKEN> --limit 100
