Extra brackets automatically added during AI autocompletion with Continue.dev extension

Tái hiện vấn đề với Continue.dev bằng cấu hình Codestral trong Robertor.java, sau đó so sánh việc chèn phần hoàn thành mã với VS Code gốc hoặc GitHub Codespaces. Bắt đầu bằng cách lần theo điểm vào chèn văn bản của ghost-view được đề cập trong báo cáo; hoàn thành khi việc chấp nhận tính năng tự động hoàn thành không còn thêm một dấu ngoặc thừa.
