Remove redundant grid calculations in module_zone and fix clean-all in Makefile

[Copilot]

Two issues flagged in code review: module_zone.scad was recomputing grid dimensions already defined in parameters.scad, and clean-all was a no-op alias for clean.

Changes

• module_zone.scad: Replace local grid_w/grid_d recomputations with direct references to bay_grid_width/bay_grid_height from parameters.scad

  // Before
  grid_w = bay_grid_cols * (bay_unit_size + bay_wall) + bay_wall;
  grid_d = bay_grid_rows * (bay_unit_size + bay_wall) + bay_wall;
  
  // After
  grid_w = bay_grid_width;
  grid_d = bay_grid_height;

• Makefile: clean-all was identical to clean (just delegated to it). Now removes the entire $(RENDER_DIR)/ tree — including assembly/ exploded-view outputs not covered by clean. Updated help output to reflect the distinction.

  clean-all:
      rm -rf $(RENDER_DIR)

Pull request overview

Diese PR räumt redundante Berechnungen in den OpenSCAD-Enclosure-Dateien auf und verbessert das Build-/Cleanup-Verhalten im Enclosure-Makefile, damit generierte Render-Artefakte zuverlässiger entfernt werden können.

Changes:

• module_zone.scad: Nutzung der in parameters.scad zentral definierten Grid-Abmessungen statt lokaler Neuberechnung.
• Makefile: clean-all entfernt nun den kompletten $(RENDER_DIR)-Baum (inkl. assembly/), und help unterscheidet klar zwischen clean und clean-all.
