Fix base64 encoding for browser environment
The bufferToBase64 function from @binect/js expects Node.js Buffer objects but was receiving browser ArrayBuffer, causing "[object ArrayBuffer]" to be sent instead of valid base64. Use browser-native btoa() instead. Also updates tests to work with @binect/js integration. Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
