fix: resolve all shellcheck errors

- Replace 'A && B || C' patterns with proper if-then-else statements (SC2015)
- Add check_for_virtualbox function to invoke prompt_for_virtualbox_challenge (SC2317)
- Fix install_launcher function to escape variable in heredoc (SC2119/SC2120)
- Apply shfmt formatting to ensure consistent style

Fixes 7 SC2015 violations, 1 SC2317 violation, and 1 SC2119/SC2120 pair.
All 79 shell files now pass shellcheck without errors.
