* Undo: what is hidden lives in the snapshot, so hiding is a step (#2219)
`Session::execute` records a step only when the document `Arc` changes, and what is
hidden lives in `Session::visibility` — saved with the design, but outside the
document. `browser.visibility` was also declared `.noundo()`, and `Snapshot` had no
field for it, so even a recorded step could not put a hidden body back: undo went to
the command before the hide and left it hidden (#2219).
`Snapshot` and `Checkpoint` now carry the `Visibility`, `go_to` restores it, and
`Session::execute` treats a visibility change as a change of its own. That change is
display-only, so it refreshes the view with a revision bump (`refresh_display`)
instead of evaluating a model a hide does not touch.
The command also takes `folder: "all"` (every body, sketch, construction item, origin
item and joint, plus the browser folders and occurrence hides) so Show All can be one
step, and asking for the state an item already has no longer reorders the hidden
lists: a redundant hide is not a step and leaves no unsaved changes.
* Show/Hide: the menus run browser.visibility, so the history has it (#2219)
The hide and show actions wrote `session.visibility` directly instead of running the
command: the body and face menus (`ui.hide` / `ui.show`), the `V` key
(`context_menu::toggle_visibility`), the browser rows' eyes, the Origin rows and
`ui.originAll` / `ui.originPart`. The engine could record a step and there was
nothing to record — which is why the release still answered "nothing to undo" after
hiding from the Browser.
They all run `browser.visibility` now (the repo rule that the UI acts through
commands), and `ui.showAll` is that one `folder: "all"` call, so Show All is one undo
step rather than three. `docs/occurrence-workflows.md` says what visibility does in
the history.
* assembly(feat): ground first parts and drag free joint chains
Ground the first top-level part when it is created and let face dragging reposition free occurrences or any member of a floating joint chain in one undo step. Preserve exact repeated-placement frames, joint values, modifier selection and Escape cancellation. Keep the accumulated fixture, viewport layout and documentation integration fixes from the existing PR.

* assembly(fix): update movable fixtures for first-part grounding
Accept the documented grounded override in component creation, explicitly free movement fixtures, and keep linked clipboard pastes movable even in an empty document. Cover first and reused linked pastes, default insertion grounding, and single-step undo in the existing link tests.

* assembly(test): keep the motion-cost crank free
Unground the first component in the document-level joint-face measurement fixture so its motion samples can rotate after first-part grounding. Preserve the rotation and shared-measurement assertions that caught the Linux CI failure.

* assembly(test): free the frame placement fixture
Create the frame-member placement fixture ungrounded before moving it above its root sketch. Keep its world-space member assertions while respecting first-part grounding in the frame tests added on main.

Hidden bodies, occurrence placements, sketches and origin items are saved with the design and come back when it is reopened. Visibility is still not an undo step, but hiding or showing something now counts as an unsaved change. Additive field under format 16. Fixes#531.

Record ownership transfers in the timeline so earlier Join/Cut membership,
world placement, machining data and styles survive component moves, edits,
independent copying, undo and reopening. Preserve pending positions in history
snapshots and keep constructor transfers ordered during feature redefinition.
Retain shallow sheet pockets and exact planar intersection islands through
unfold/refold, with depth-aware flat previews and DXF export. Store explicit
3D wire coordinate spaces and migrate known legacy provenance without moving
saved points or analytic fits.
Infer unique eligible cylindrical Emboss targets, align Revolve manipulators
with actual extent geometry, and discard obsolete preview errors after input
correction. Certify constructed and immutable imported face styles using exact
source metadata while preserving legacy face names. Upgrade designs to format10
with bounded validation and geometry-preserving legacy migration.
Persist typed sketch dimensions and bounded ordered configuration rules in format 8. Use exact occurrence paths and source identity for editing, movement, appearance, and mass. Preserve sheet material regions through cutting, folding, and exact DXF export; retain nested cavities and material islands.
Validation: cargo xtask ci passed, including 368 engine tests, 178 UI tests, 68 UI scenarios, 136 kernel tests, and the 10-crate wasm check. Actual preview workflows and legacy format-7 origin-corner reopening were inspected.
