fix: correct redirect parsing to use destination URL instead of status code

[jos-felipe]

Summary

• Fixed critical bug in redirect parsing where status code was used instead of destination URL
• Enhanced configuration with comprehensive route definitions
• Cleaned up obsolete test files and added project documentation

Changes Made

• Config.cpp: Fixed parseLocationBlock() to use tokens[2] (destination URL) instead of tokens[1] (status code) for return directives
• default.conf: Updated with comprehensive route configuration including static content, uploads, CGI, and redirect routes
• Cleanup: Removed obsolete www/test.php and www/test.py files
• Documentation: Added CLAUDE.md with project guidelines and build instructions

Bug Fix Details

Before: Location: 301 (incorrect - status code)
After: Location: / or Location: /index.html (correct - destination URL)

Test Results

✅ Both redirect routes tested with curl and Playwright:

• /old-site/ → / (301 redirect)
• /legacy/ → /index.html (301 redirect)

Test Plan

• Build server successfully
• Test redirect routes with curl (manual headers check)
• Test redirect routes with Playwright (browser navigation)
• Verify no redirect loops occur
• Confirm proper HTTP 301 responses with correct Location headers
