improve: enhance lint.sh script with debugging and artifact cleaning

- Add cargo clean between toolchain switches to prevent build conflicts
- Add toolchain debugging information showing versions and target directory
- Add visual separators and emojis for better script output readability
- Prevent future shellcheck 'no shell scripts found' issues from toolchain conflicts
- Improve error diagnosis with detailed version information display
