Commands: ids leave out an object listed with a group that holds it, as the selection does

Commands that read the selection through edit::selected_roots leave
out an object whose group is also selected (edit::roots_of). Fourteen
places that read `ids` kept an object listed together with its group.
Given ids that list an object and a group that holds it, Make Repeat
failed with "no such object", New Symbol failed or stored the object
twice in the symbol, and object.transform moved it twice (20 pt for a
10 pt move).

These places now pass explicit ids through edit::outermost, which
drops an id whose ancestor is also listed, with the filter that
roots_of runs on the selection (now edit::without_inner). Nothing else
is dropped or replaced: unlike roots_of, it keeps layers and
compound-path members. A list without nesting gives the same result as
before. Commands that take both ids and the selection as listed, such
as paint.setFill without item, are unchanged.

     Anchor Align moves the selected points to their bounds or the artboard (#1180). Repeating it, or moving by at most 1e-9 pt on both axes as whole-object Align does, leaves the document, Undo, Redo and saved state unchanged; actual moves still take one undo step. `crates/engine/src/tests.rs` covers repeated alignment, rounding-only alignment, unchanged handles, saved state, command recording and Undo/Redo.
     A symbol instance is measured by its symbol's art, as its transform places it, for clicks, the marquee, the bounding box, the Transform panel, Align and Distribute (the art's strokes too with Use Preview Bounds), Fit to Artwork Bounds, exports of the art, thumbnails and canvas culling; one whose symbol is missing is measured as the 20 × 20 square around the origin.

+    A command that leaves out an object selected inside a selected group also leaves it out when `ids` list it together with a group that holds it. Make Repeat and Live Paint no longer fail on such a list, New Symbol no longer stores the object twice, and `object.transform` no longer moves it twice.
   - **Compound paths:** Make keeps the backmost object's appearance and each contour; selecting a member in Direct Selection reads and changes the compound's fill rule in Attributes. Direction remains a per-member edit. Rendered holes, unchanged contour geometry, no-op history and Undo/Redo are covered by `engine/tests/compound_attributes.rs` (#1197). Behaviour reference: [public compound-path documentation](https://helpx.adobe.com/illustrator/desktop/manage-objects/reshape-transform-objects/create-compound-paths.html). Make Compound Path on a group (such as outlined type) keeps the paint of its backmost path instead of drawing nothing, and compound paths joined into one keep their holes (#1537).
   - **Saved selections:** Select ▸ Save Selection… asks for a name and keeps the selection in the document (saved with the file, undoable, up to 25); each one is listed at the bottom of the Select menu and a click selects its objects again; Edit Selection… lists them to rename or delete, applied together on OK. A file's saved selections are capped and checked against its objects when it opens. Not yet: Update Selection and the Layers panel's saved-selection menu.
   - **Drawing modes:** in Draw Inside, a double-click with a selection tool outside the object being drawn into sets the drawing mode to Draw Normal, as Shift+D does.
