Code review items (raistlin7447):
1. PrintObject::slice() zeroes m_belt_min_z, m_belt_global_z_offset and
m_belt_global_xy_correction before slicing. They were only written in belt
mode, so a project switched to a normal printer, or whose tilt axis was set
to None, kept the old offsets and shifted the adaptive infill octree and the
organic support layers by them.
2. TreeModelVolumes shifts the support blockers into the raft-offset index
space; a test now pins the index the blocker lands on.
3. The final-alignment clamp in libnest2d is opt-in (NfpPConfig::clamp_to_bin)
and arrange sets it for belt printers only. Printers with an off-centre
best_object_pos keep their alignment; a flat-bed test pins that.
4. The preview's belt view follows the loaded G-code, not the selected printer:
GCodeProcessor carries the file's belt keys (and, for a belt file, its bed)
into export_config_for_render(), and GCodeViewer enables the belt view from
the header tilt.
5. belt_shift_layer_grid() also shifts the cached belt floor and the global Z
offset, so a support-only or brim-only change after the purge-prism snap
matches a fresh slice.
6. update_print_fff_config() resets raft_layers and draft_shield on a belt
printer instead of only greying out the fields Print::validate() rejects.
7. GCodeWriter takes a first-layer point test instead of the FirstLayerPlane;
GCode installs one that measures from the belt surface, like its
extrusions, so the first-layer travel speed and the second-layer
temperature change no longer depend on the gcode_remap_* convention.
8. belt_brim_clip_leading_edge() is exported and called by both the generator
and the test.
9. Both phong.vs shaders use slope.up_direction for the overhang highlight.
The pre-slice and G-code axis remaps are gated on belt_printer through
BeltTransformPipeline::axis_remap_enabled(), so belt keys left in a profile
cannot change a non-belt print.
Tests requested in the review: belt-only keys at non-default values leave
non-belt G-code unchanged; switching a sliced project from belt to non-belt
(and tilt axis None) matches a fresh slice; a support-only change on a belt
purge print matches a fresh slice; non-belt start G-code moves keep the
first-layer Z in the processor; the belt brim's segment count catches a band
emitted twice.
The belt-to-non-belt test exposed an unrelated gap: invalidate_step(posSlice)
re-invalidated posSupportMaterial but not posSimplifySupportPath, so after
any re-slice the regenerated support paths were exported unsimplified.
posSimplifySupportPath is now in that list.

The clang-tidy job on #14394 fails on 129 misc-include-cleaner findings:
the belt sources and tests use std::, Eigen, Point/PrintConfig and
BeltBrim symbols without including the header that provides them, which
only compiled because the precompiled header supplied it. Every include
the job names is added, in each file's existing include style ("../" in
the GCode/ and Support/ subdirectories, quoted libslic3r/ paths in the
GUI and tests). No code changes.
Verified with scripts/clang_tidy_diff.py -p build-tidy --base eb5b9a77b9
(SLIC3R_PCH=OFF compile database, clang-tidy 22.1.8): no findings left.

* initial commit
* fix upper bounds for assemblies
* significantly less Z shift issues, still not quite tamped down yet though
* add instrumentation to logs
* finally found the issue
* update printer defaults
* minor logic swap
* first attempt, has a race condition
* fixed the offset issue
* found a solution, I think things work now (at least once I quash this race condition)
* still chasing down race conditions
* add manual shear / scale order strategy swap
* tweak manual shear, fix ui uninitialization crash
* fix z height / g-code desync issue
* fix shear then scale cutoff planes
* getting closer
* fix support termination planes
* fix incorrect offsets in shear-then-scale mode
* test - fix overextrusion due to model/layer scale
