Features

Ctrl+G (Cmd+G): makes a selection of several an ObjectGroup that its systems hold
Ctrl+G on some parts of one group: a group inside it, the outer group changed in place
Ctrl+Shift+G: ungroups a group made in the window, or dissolves it into its parent group
Ctrl+click on a part of the same group adds it while parts of one group are selected
Cards: action "group" on a selection of several, "ungroup" on a group made in the window
Ctrl+drag from the background: rectangle adds the visible top-level objects whose center lies inside
Ctrl+C, Ctrl+V: copy groups of catalog components and several selected objects
Pivot of a group or a selection of several: a dot shows it, dragging the dot moves it
Card row "pivot": typed x/y/z, "pick" a part (also inside a subgroup), "center" of the box; set_pivot3d!(gui, group, p)
export_script, export_changes: write the groups made in the window, delete!/push!/set_pivot3d! for changed script groups

Bugfixes

Inspector: the button "<" of a part covered the actions, e.g. "parts >"

Doc changes

live_view and "Kinematic controls": grouping keys, grouping within a group, the selection rectangle, the pivot
"Adding and removing components": copying groups, export of groups made or changed in the window
Example of the empty table opens in the app layout, as its comment says
Agent skill: SKILL.md, API.md updated

Internal changes

Needs push!/delete! of ObjectGroup from BeamletOptics master (Feature: objects can be added to and removed from an ObjectGroup JuliaPhysics/BeamletOptics.jl#183)

The card (compact) and the inspector (app) of a _MultiSelection show "N objects", the subtitle "Selection", a row per object whose button selects it alone, the actions hide and remove, no pages and no pin. Hiding hides all objects (shows all if all are hidden); hidden objects leave a selection of several. A click on an object of a group of the selection selects it alone. _label(::LiveView, ::_MultiSelection) resolves the ambiguity with the generic _label.

… reset, history (W1) Ctrl+click (Cmd on macOS) adds the top-level object to the selection or removes the member; its press is consumed, such that Camera3D does not reset. A drag on any member, the gizmo and the keys move the selection as one, without snapping; Esc deselects it, Backspace resets all its objects as one undo action; the spectator mode restores it.

The tree sets `toggled` instead of `clicked` for a click on a label with Ctrl or Cmd held at the press; `_tree_toggle!` toggles a movable object via `_toggle_select!`, other rows behave like a plain click. `_set_selected!` takes a vector of keys (`selected_keys`), highlights all their rows and scrolls to the last added one; `_on_selected!` reveals and highlights all objects of a selection of several.

…_is_movable, _drag_snaps trait (W1) The methods for KinematicController and _MultiSelection are self-contained, since the untyped ones of the W0 core are removed; _drag_snaps is a trait by dispatch. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
