test: Add tests for app/ - #59

Node.js 20 is deprecated. The following actions target Node.js 20 but are being forced to run on Node.js 24: actions/cache@v4, actions/checkout@v4. For more information see: https://github.blog/changelog/2025-09-19-deprecation-of-node-20-on-github-actions-runners/

These files were overwritten during the `brew link` step:

The following taps are not trusted: aws/tap azure/bicep hashicorp/tap Homebrew is currently ignoring formulae, casks and commands from these taps because tap trust is required. Prefer trusting only the specific formulae, casks or commands you need. Trust installed formulae from these taps with: brew trust --formula azure/bicep/bicep brew trust --formula hashicorp/tap/packer Trust other specific casks and commands with: brew trust --cask <user>/<tap>/<cask> brew trust --command <user>/<tap>/<command> Whole-tap trust is broader and includes all current and future formulae, casks and commands from the listed taps. Trust whole taps with: brew trust aws/tap azure/bicep hashicorp/tap Untap them with: brew untap aws/tap azure/bicep hashicorp/tap To disable trust checks: export HOMEBREW_NO_REQUIRE_TAP_TRUST=1 This is not recommended and will be removed in a later release. For more information, see: https://docs.brew.sh/Tap-Trust
