Subject: [PATCH] feat(workflows): implement timeout for pacman installation

This update introduces a timeout mechanism for the pacman installation process in the app builder workflow. If the installation does not complete within 30 minutes, it will terminate and log a timeout message, improving the robustness of the build process.

- Adds a timeout for the pacman command to prevent indefinite hangs
- Implements a heartbeat to monitor the installation progress
- Provides clear error messages for timeout and failure scenarios
