====== std.error ======

Vollständige POSIX-errno-Konstanten (''EPERM'' bis ''EHWPOISON'', Codes 1–133) als Lyx-Konstanten sowie Hilfsfunktionen zur Fehlerauswertung: ''GetErrorMessage(code)'' gibt den menschenlesbaren Fehlertext zurück (z.B. ''ECONNREFUSED'' → ''"Connection refused"''), ''CheckSyscallError(result)'' prüft ob ein Syscall-Rückgabewert einen Fehler signalisiert, und ''GetSyscallErrorCode''/''GetSyscallErrorMessage'' extrahieren den errno-Wert aus negativen Rückgabewerten.

Einsatzbereiche: alle Units die direkt mit POSIX-APIs interagieren (''std.fs'', ''std.net.*'', ''std.process'', ''std.thread''); Fehlerdiagnose in systemnahen Programmen.
