Subject: [PATCH] Fix dasu_panel.py to work as an installable Blender addon

Add bl_info dict so Blender recognises the file as an addon, and replace
the bare module-level registration code with proper register()/unregister()
functions. Previously the addon would install but not appear in the list
and threw a RuntimeError on enable.

Generated with the assistance of an AI coding tool.
