Subject: [PATCH] fix: Install Rust for actual user when running with sudo

**Problem**: When setup script runs with sudo, Rust was installed in
root's home directory (/root/.cargo), making it inaccessible to the
actual user running the script.

**Solution**:
- Detect actual user using $SUDO_USER environment variable
- Use 'su - $ACTUAL_USER -c' to run Rust installation commands
- Install Rust in the actual user's home directory (~/.cargo)
- Run all rustup commands (default, update, target add) as actual user

**Testing**: Designed for 'mesut' user running 'sudo ./setup.sh 8'

This ensures Rust is accessible to the user and can be used for
SDK compilation without permission issues.
