This commit introduces a Dockerfile to create a reproducible build
environment for the Hyperion Grabber project. This aims to address
persistent compilation issues related to header file discovery on
the host system.
The Dockerfile sets up an Arch Linux base image, installs necessary
dependencies (Qt5, PipeWire, GLib, CMake, etc.), copies the source
code, and attempts to build the project within the container.
This approach provides an isolated and consistent environment, which
should help in diagnosing and resolving build-time problems.
