Pencil: the straight-line cursor's description names the Alt exception and the Constrain Angle

The PencilStraight entry in cursors.toml now says the cursor does not show while Alt is also held with Alt key toggles to Smooth Tool on, and that the line follows 45° steps from the Constrain Angle. The parity doc says the Option/Alt straight line waits for #3959.

    With the Blob Brush, Shift held during a drag keeps the stroke on the horizontal or vertical line through the press point, whichever is nearer to the pointer (90° steps from the Constrain Angle preference), and the points dragged since Shift went down move to the other line when the pointer crosses to it; the points dragged while Shift is up follow the pointer.
    Curvature point markers are circular, with no direction handles. While drawing, its own point feedback replaces generic selection markers; existing paths use the selection overlay, including partial selections and Hide Edges. Anchor Size applies, and Direct Selection and Pen retain their handles. The real egui-frame regressions in `crates/ui-egui/src/canvas.rs` verify marker positions, counts and unchanged documents (#1236, in part); the existing-path interpolation request remains open. The curve through the points (`curvature_spline` in `crates/tools/src/draw2.rs`) makes each stretch of three points follow the circle through them: a smooth point's handles lie along that circle's tangent, each `chord / (3 cos²(α/2))` long (α between handle and chord, capped at 90°), and the ends of an open path mirror their neighbour's tangent in their chord, so a J or a U curves evenly, a turn tighter than 30° comes to a point, and uneven spacing doesn't loop; the rubber band, a dragged or inserted point and `path.convertAnchor` to smooth use the same rule, while the Pencil's fitting keeps its own; `tests_draw2.rs` checks that the rubber band is the path the click makes (#1236, in part). The Smooth tool smooths only the stretch of path under the drag (#1547, fixes #1512).
    While Alt is held, the Paintbrush, and the Pencil with Alt key toggles to Smooth Tool off, show a closing cursor (a crosshair with a ring); releasing the mouse button with Alt still held closes the path.

    While Alt is held, the Paintbrush (before a press and while drawing) shows a closing cursor (a crosshair with a ring), and so does the Pencil with Alt key toggles to Smooth Tool off when Alt is pressed after the drag starts; releasing the mouse button with Alt still held closes the path. A Pencil drag started with Shift or Alt held draws a straight line instead, which stays open.

With Option/Alt held at the press and Alt key toggles to Smooth Tool off, the Pencil draws a straight line at any angle, whose ends snap to Smart Guides, and it stays open when Alt is still held at the release; Shift and Alt together keep the 45° steps (#3799). The straight-line cursor remains.
