Port of the snaporca CAD work to the mainline fork.
- Onshape default planes (XY/XZ/YZ) at the bed centre (transparent, labelled);
modeling origin unified to the bed centre (CadDocument::modeling_origin);
world-axis triad moved to the bed centre on the Design canvas only.
- Datum plane: clickable ghost-plane base pick + draggable offset arrow.
- Slot: dims reassessed to inter-centre distance / radius / angle; fixed the
duplicate cap-arc radius quote.
- Hole: 3D cube move-handle on the face; binds to the face on the first click;
decluttered side-distance construction lines.
- Thread: derive the M spec (diameter/pitch/depth) from a picked cylindrical
surface or circular edge (GeometryEngine::circle_of_edge); fuse the helical
ridge onto the existing body; MakePipeShell fixed-binormal sweep (uniform, no
twist) + self-intersection/param guards.

Mirror of snaporca-cad 75045ff. Re-editing an Extrude spawned a NEW misplaced
box: build_candidate() rebuilt the feature from live tool state, but GUI
extrudes store their profile as `entities` (sketch_ref = -1) which the edit
card never restores, so the candidate had an empty profile and replace_feature
swapped in a degenerate extrude. Fix: when editing, seed the candidate from the
feature being edited and skip add-time structural re-derivation (profile source,
up-to-face, target body); the card still overrides scalar params.

Mirror of snaporca-cad a82cb0d. snaporca-88g — three [CadDocument] tests
proving recompute() replays the whole timeline, so editing any feature (not
just the last) rebuilds downstream: mid-timeline extrude edit -> fillet
rebuilds; first-feature sketch edit propagates the chain; the same survives
serialize_recipe()/deserialize_recipe(); a sketch->extrude->hole->chamfer
chain rebuilds hole+chamfer on a mid-edited extrude. All 3 pass (34 assertions,
Catch2 v3). on_edit_feature edits the tree-selected feature at any position
(13/16 types); Import/Boolean/Cut get a status message instead of a silent
no-op (full dialogs = follow-up snaporca-nu9).

Mirror of snaporca-cad 0f53a09. DesignPanel.cpp pinned every _L() to
wxString::FromUTF8 via a TU-local #define, hardcoding English and bypassing
the gettext catalog — a hard review-blocker for upstream (OrcaSlicer ships
~20 locales). Remove the override so the 463 _L("...") call-sites route
through the real Slic3r::GUI::I18N::translate (wxGetTranslation). All args
are string literals; untranslated strings fall back to the source msgid, so
English is byte-identical while other locales now translate when .po entries
exist. xgettext scans source text, so .pot extraction is unaffected.

Dual-fork mandate: port the parametric-recipe 3MF persistence from
snaporca-cad commits ed19eac+147e1c4 so a saved project reopens with the
editable CAD feature tree, not just the baked mesh.
Shared kernel/format/GUI (identical to snaporca-cad):
- CadDocument serialize_recipe/deserialize_recipe (cereal BinaryArchive,
versioned) + CadFeature split save/load + imported_solid<->BRep string.
- Model::cad_recipe carried through 3MF zip entry Metadata/SnapOrca_cad.bin
(writer + binary-verbatim reader branch).
- DesignPanel on_commit() stamps the recipe; on_tab_shown() rehydrates a
loaded project via load_recipe() (deserialize -> feed_bodies + refresh_tree).
Mainline-only adapters (no snaporca-cad counterpart — Catch2 v3 vs v2):
- tests/libslic3r/test_caddocument.cpp: <catch2/catch_all.hpp> +
`using Catch::Approx;` (v3 scopes Approx under Catch::).
- tests/libslic3r/CMakeLists.txt: register test_caddocument.cpp (the
original CAD port had left it out of the test build).
Verified on behemoth (snaporca-deps toolchain): libslic3r_tests clean;
[CadDocument] 17/18 (only the pre-existing tangent-to-circle SIGABRT fails,
identical to snaporca-tkz); K1 serialize round-trip + version-reject pass
(13 assertions); new [3mf] "CAD recipe blob survives a 3mf save/load cycle"
passes byte-for-byte; orca-slicer GUI links clean (186/186, DesignPanel.cpp
compiled). Interactive :10 click-through pending (no Design-tab automation).
