NativeCAM 2.0b — Python 3 & GTK3 port for LinuxCNC 2.9 / Debian 13 Trixie

Hello everyone,

I would like to announce the release of NativeCAM 2.0b — a community port 
of the original NativeCAM (by Fernand Veilleux) migrated to Python 3 and GTK3.

The original NativeCAM was written for Python 2.7 / GTK2, which is no longer 
available on modern distributions. This port makes it fully compatible with 
LinuxCNC 2.9 on Debian 13 Trixie.

--- What's new in 2.0b ---

* Full Python 3 / GTK3 migration
* New: Side Drill feature — horizontal drilling from Top / Bottom / Left / Right 
  faces of the workpiece, designed for multi-spindle machines like Biesse Rover
* New: Horizontal tool visualization in AXIS — tool rotates correctly in the 
  3D view when a side spindle is active (uses tool table Q column: 10-13)
* Fix: Phantom GTK popup windows no longer remain on screen after LinuxCNC exits
* Fix: About dialog now shows version correctly (Python 3 bytes decode bug)
* Fix: Validation Messages menu now uses checkboxes showing current state
* Debian packaging updated for modern build tools
