D-Series Selectable Body Lift Pack v0.3 (test build)

Built from the current pickup.zip supplied by the user, with D-Up visual hardware from Torsion's old mod.

MAIN CHANGES FROM v0.2
- Corrected "visor" handling: this now targets the INTERNAL movable sunvisors, not roof/lightbar accessories.
- The dashboard/interior used by the body-lift frames is a lift-aware copy of the current vanilla interior.
  Its Sunvisors slot gets the exact same nodeMove9 Z offset as the cab, fixing the floating visor props.
- Removed the mistaken external "Lifted Visor / Roof Lightbar" and factory front-valance passthroughs.
- D-Up's original 5-inch gap hiders / vanity pieces / lift hardware remain the same model size and are enabled
  on all 1in, 2in, 3in, 4in and 5in lifts. They are visual-only (no collision mesh).
- Rebased the frame copies on the supplied CURRENT vanilla D-Series frame files instead of the old D-Up frame copies.
- Added current heavy-duty long-bed wheelbases.

BODY-LIFT-READY FRAME OPTIONS
- Heavy Duty Frame (regular cab + standard bed)
- Heavy Duty Extended Frame (extended cab + standard bed)
- Heavy Duty Crew Frame (crew cab + standard bed)
- Heavy Duty Long Bed Frame (regular cab + long bed)
- Heavy Duty Extended Long Bed Frame (extended cab + long bed)
- Heavy Duty Crew Long Bed Frame (crew cab + long bed)

Each frame exposes Body Lift Height: 1in / 2in / 3in / 4in / 5in (3in default).

TESTING
1. Remove/disable v0.1 and v0.2 so they do not overlap.
2. Put this ZIP in the BeamNG user mods folder.
3. Spawn a D-Series and select a Frame ending in "Body Lift Ready".
4. Change Body Lift Height.
5. Check the internal sunvisors both folded up and pulled down.
6. Check regular/ext/crew standard beds and all three long-bed frame variants.

NOTES
- D-Up hider/bracket meshes are intentionally still the original 5in dimensions at smaller lift heights.
- Because the long-bed variants did not exist in D-Up, the same original D-Up bed hider is reused and positioned
  on the current long-bed frames. It may not cover the full long-bed gap perfectly, but it is non-collision visual geometry.
- Current vanilla frame/body geometry remains provided by BeamNG; this mod only carries modified JBeam copies and the old D-Up visual DAE.
