- Replace grep -oP (Perl regex) with portable sed — fixes "grep: invalid option -- P" on macOS
- Add sedi() wrapper for cross-platform sed -i (BSD vs GNU)
- Detect macOS via uname and use apple-darwin binary suffix instead of linux-musl
- Add is_native_binary() helper: checks both ELF (Linux) and Mach-O (macOS)
- macOS env vars: use launchctl setenv + /etc/codex-env.sh + ~/.zshrc source line
- Linux env vars: keep /etc/environment + /etc/profile.d/ as before
- Wrapper script uses dynamic ENV_FILE path instead of hardcoded /etc/profile.d/
- Fix SUDO_USER handling for correct ~/.zshrc path when run via sudo
- Uninstaller: also remove .codex-bin, /etc/codex-env.sh, launchctl vars, rc file entries
- Uninstaller: scan /Users/* on macOS instead of /home/*
- Fix CRLF line endings in ucodex_uninstall.sh
