- Prompts for issue description with multiline input support
- Auto-translates foreign languages to English
- Generates formatted GitHub issue using Claude Agent SDK
- Streams character count with animated progress
- Auto-sanitizes paths for privacy
- Automatically opens GitHub issue form with pre-filled title and body
- Saves timestamped report locally

Usage:
  npm run bug-report              # Interactive bug report
  npm run bug-report --no-logs    # Skip logs for privacy
  npm run bug-report --verbose    # Show all diagnostics
  npm run bug-report --help       # Show help

- scripts/bug-report/cli.ts - Interactive CLI entry point
- scripts/bug-report/index.ts - Core logic with Agent SDK
- scripts/bug-report/collector.ts - System diagnostics collector
