* modelcraft-io: the .modelcraft file (modelcraft/1), atomic writes, autosave storage
A stored ZIP of a manifest (format tag, geometry sources with SHA-256,
part sizes and hashes), the model definition as stable pretty JSON, the
mesh and geometry tags in a compact binary part, and the journal one
command per line. Reading caps every size, checks every checksum and
replays the model through its checked methods. Model::without_mesh and
empty mesh fields left out of the model's JSON; geometry::read_file.

* engine: undo/redo on the journal, file.open/save/save_as, autosave and recovery
CommandSpec gains a kind: Model commands are journalled and become undo
steps; Session commands (file.*, edit.*) manage the session. Undo history
is bounded by steps and estimated memory. Geometry sources are recorded
with content hashes and reopened on file.open (missing or changed files
are warnings). Desktop app autosaves every 30 s and reports recoverable
models; Ctrl/Cmd+Z and Shift+Z/Y undo and redo.

* simplify: shared path parameter, one load path for open/recover, history accounting in History
Session commands skip the per-command model copy; saved revision is an
Option; journal written from borrowed entries and read without an
intermediate tree; backups copied by the file system; recovery lock and
error helpers; geometry file wrappers use read_file.

* model: split nodes and elements into a mesh module (no behaviour change)

* model: sets by geometry name, materials and units, sections, couplings, BCs, loads, steps and the check
Sets bind to persistent geometry names through the mesh's geometry tags
(element, element face/edge and node classification) and resolve against
the current mesh, so they survive a remesh. Steps list their active loads
and boundary conditions explicitly. Model::check names every missing or
bad item; Model::resolve gives the writers' view.

* engine: model definition commands (sets, materials, sections, RPs, couplings, BCs, loads, steps, tags, check)
Each definition has create/edit/delete with its model JSON form as
parameters; model.step.activate and model.activity drive the explicit step
table; mesh.tag records where the mesh lies on the geometry; model.check
and model.set.resolve report against the current mesh. Hostile params run
against an empty and a fully defined session.

* model, engine: review cleanups
Validated deserialization (a file replays through the checked methods),
interned geometry tags by index, set resolution with tag bitsets and sorted
vectors, one delete policy (a load or BC listed by a step is in use),
shared helpers (context, remove_existing, step_mut, opt/req/name/listed),
dead code removed, Resolved without a per-element section map.

* model: mesh-independent force distribution, tractions, stable reference point labels
Force and moment on a set default to a total, split by consistent nodal
weights over the set's faces (or equally over a node set); per_node is an
explicit opt-in. Traction is force per area. resolve() expands them to
nodal values for every writer and the solver. Reference points keep a
stored node label taken from the top of the label range.

One end-to-end slice first (sets bound to SolidCraft names, materials, sections, BCs, loads,
steps, three deck writers, own solve) on tet meshes; then structured hex (sweep, mapped,
automatic decomposition) before octree all-hex; then contact, materials and explicit, and
post-processing. docs/parity.md lists capabilities by milestone, with the areas where we aim
to be better than Abaqus/CAE.
