fix: add system dependencies and remove Windows target

- Add apt dependencies for Linux: cmake, libssl-dev, libsasl2-dev, pkg-config
- Add homebrew dependencies for macOS: cmake, openssl, cyrus-sasl, pkg-config
- Remove Windows target (OpenSSL/SASL deps are complex on Windows)
- Remove powershell installer (no Windows builds)
