Windows: a maximized window stays clear of a taskbar on the top or a side

With the taskbar on the top edge, a maximize, a restore from the
taskbar or a drag to the top of the screen showed a classic title bar
above the app bar (#3242, #3723, #2072). The guard that keeps the
custom title bar's window borderless trimmed only the bottom of a
parked maximize to the work area, so with the taskbar on the top or a
side the window still covered it, and the strip between the window's
edge and the client area, which winit keeps on the work area, was
drawn as an old-style caption.

The guard now moves a parked maximize inside the work area on every
edge, keeping the resize border it was parked with, which it reads
from an edge without a taskbar. A rect it already moved, a dragged or
snapped window and a monitor with no reserved taskbar are left alone.
The move uses SWP_FRAMECHANGED and SWP_NOCOPYBITS and invalidates the
window, so the whole window is drawn again, and the style strip uses
SWP_NOCOPYBITS too. This ports FredApps's fix in PhotoCraft
(storytold/photocraft#5237).

   - Cmd/Ctrl+Alt+N (`file.newWithoutDialog`) makes a document without opening the New Document dialog, on the key the reference app's [Default keyboard shortcuts](https://web.archive.org/web/20260726060015/https://helpx.adobe.com/illustrator/using/default-keyboard-shortcuts.html) page lists for making a new document with no New Document dialog box. The page does not say which settings the document gets. VectorCraft gives it the settings the dialog opens on (the first Recent entry, or the Print category's Letter while Recent is empty) and the next untitled name.
   - Shortcut sets other apps save as text (`.kys`) open in Import Shortcut Set from File › Open, from Edit › Keyboard Shortcuts › Import… in the desktop app, or from a drop on the window. It matches each entry to a tool, command or panel by name and decodes the file's key and modifier codes where VectorCraft's default shortcuts agree on them; the user answers the rest, and Apply fills the Keyboard Shortcuts dialog's working set. The answers are kept with the preferences for the next import (`shortcutSet.read`, `importMatches.*`).
   - On Windows and Linux the app bar is the window's title bar (its own minimize, maximize and close buttons, drag to move, edges to resize), with the dragon app icon as the brand mark; dialogs and menus size to their content. As on a native menu bar, once one menu is open, moving the pointer onto another title opens that one.

   - **Shaper:** uneven squares and rectangles become live rectangles even when drawing begins mid-edge. Recognition uses uniformly spaced samples and closed-loop corners, fits rectangle edges/angles rather than requiring a nearly perfect bounding-box fill, and includes the pointer-release position. Rectangles/squares and ellipses snap to 45° steps, hexagons to 90°, and triangles point up or down; lines keep their free angle even with Shift. Shaper Groups retain the live originals, merge regions with the gesture-origin fill, punch fills independently from strokes, remove boundaries on exiting scribbles and trim protruding stroke pieces. Source moves/resizes re-evaluate the result in the same undo step; double-click enters construction editing, and with the Shaper or Selection tool a click on the arrow widget beside a Shaper Group's original shapes switches the group between Face Selection and Construction mode. Native save/reopen, face recoloring, Release and Expand are covered. Finer gesture heuristics remain.
   - **Selection:** Selection, Direct/Group Selection, Magic Wand, Lasso. A Shift-drag marquee toggles what it reaches: objects with the Selection tool, anchors with Direct and Group Selection (#483); the Lasso adds with Shift and subtracts with Alt. Dragging a path segment with Direct Selection bends it when it's curved (its anchors stay) and moves its two anchors when it's straight, one undo step; the fill, Shift or Alt still pick the whole path (Alt-drag copies it).
