print an extensive long list of program names that might be useful for fulfilling the following task but might be not installed.
Include many possible alternatives. Use glob patterns to account for variability - like foo* for programs starting with foo.
For MacOS, include homebrew installable programs.
A script will then look whether there are any such programs in the PATH and the Applications folders and tell you the
matches, so that you can make a program later that fulfills the task. Print only the program names, no descriptions, as JSON.
The task is:
