Subject: [PATCH] chore: bump version to v4.5.0-rc.4 and add comprehensive test
 suite

- Added test-release.sh for core functionality testing
- Added test-edge-cases.sh for URL and header edge cases
- Added test-proxy-scenarios.sh for reverse proxy testing
- Added test-security.sh for security vulnerability testing
- Added test-installation-methods.sh for deployment validation
- Added test-all.sh master script to run all tests
- These tests would have caught issue #334 and prevent similar issues
