v0.2.1 - Accurate Per-Hop HTTP Redirect Timing

🚀 New Features

Accurate Per-Hop Response Times

• Individual redirect timing: Each redirect hop is now timed separately with accurate measurements
• Total time in header: Overall response time displayed in the card header for quick reference
• Per-hop display: Each redirect row shows its individual response time
• Final destination timing: The final response also shows its individual timing

How It Works

The HTTP adapter now follows redirects manually (instead of using curl -L), making individual requests for each hop and timing them separately. This provides accurate, actionable timing data for debugging slow redirects.

Example:

🌐 http://example.com                               411ms  ← Total

301  http://example.com                              125ms
301  https://example.com                              89ms  
200  https://example.com/                            197ms

🐛 Bug Fixes

• Removed unused TypeScript functions causing build errors
• Cleaned up git repository by excluding Rust build artifacts

🔧 Technical Details

• Refactored HTTP adapter to manually follow redirects with individual timing
• Added response_time field to HttpRedirect model (Rust + TypeScript)
• Enhanced HTTPResponse component to display total time in header
• Updated RedirectChain component with per-hop timing display
• Improved .gitignore to exclude target/ directories
