PR Summary
Replace Unix login-shell startup P/Invokes for process metadata with managed .NET APIs while preserving the existing native calls required by direct process replacement and macOS argument inspection.
PR Context
.NET 11 already provides the Linux executable path and current process ID through behavior-equivalent managed APIs. This PR uses those APIs and removes the obsolete
readlinkandgetpiddeclarations. It retainssetenvbecauseEnvironment.SetEnvironmentVariableupdates the managed Unix environment cache, not the native libc environment inherited by the existingexecvcall, and retainsexecvand macOSsysctlbecause no equivalent managed APIs preserve the startup behavior.PR Checklist
