Previously, the examples in the `cli-builder` guide were hard-coded. This made it impossible to test them and verify they are correct. This commit fixes this by converting them into a proper mini-app. In a subsequent commit, tests will be added to verify that the source code works as expected (and guard against regressions). Fixes #34314 PR Close #34362
