- Remove all emoji characters from install scripts (linux, macos) - Rewrite uninstall scripts: remove set -e, fix safe_remove to always return 0, replace ((var++)) with $((var + 1)), fix local keyword usage, add comprehensive cleanup including config.json - Fix install script QUIET_MODE/DAEMON_MODE detection to correctly handle interactive runs when old config.json exists Co-authored-by: Cursor <cursoragent@cursor.com>
