* pkg/debugdetect: add package for detecting debugger attachment Implement new pkg/debugdetect package that detects if a program is running under a debugger on Linux, macOS, Windows, and FreeBSD. Platform-specific detection methods: - Linux: Parse /proc/self/status for TracerPid field - macOS: Use sysctl with KERN_PROC_PID to check P_TRACED flag - Windows: Call IsDebuggerPresent() Win32 API - FreeBSD: Try sysctl first, fall back to /proc/curproc/status Fixes #4243 Co-Authored-By: Claude Sonnet 4.5 <noreply@anthropic.com>
