Release/v1.5.0 (#63)

* fix: use native SSL on macOS/Windows, remove OpenSSL dependency

- macOS: Use SecureTransport (via Security framework)
- Windows: Use WinSSL/Schannel (via crypt32)
- Remove OpenSSL requirement for faster compilation
- Smaller binaries and better OS security integration

* chore: bump version to 1.5.0 for optional OpenSSL feature

* docs: update CHANGELOG for v1.5.0 release
