🖼️ Build Darktable — Debian/Ubuntu Build & Packaging Script

This script automates the compilation of darktable from the master branch and generates a fully functional, lintian-compliant .deb package, including an optional debug symbols package (darktable-dbgsym).

Designed for reproducibility and compliance, it handles common packaging issues: permissions, ownership, man pages, copyright, and more — all without requiring sudo at the end.
