nnd: A Blazing Fast, Lightweight Native Debugger for Linux

Meet nnd, a Linux debugger inspired by RemedyBG, prioritizing speed and lightweight design. It boasts a TUI interface, is built largely from scratch (not based on gdb or lldb), and handles large executables efficiently (tested on a 2.5GB ClickHouse executable). nnd focuses on speed; instantaneous operations are truly instantaneous, while longer operations are handled asynchronously with progress bars. Currently, it only supports Linux x86-64 native code debugging and lacks remote debugging, multi-process support, and reverse stepping. Distributed as a single 6MB executable with no dependencies, it's easily installed via curl or built from source.
