Creator ruling: open in the upper-left of the screen with ~75px padding. The
restore path was placing the window below the fold.
RestoreWindowGeometry now ignores the saved position and calls the pure
TopLeftPlacement(workArea, w, h, padding): work-area origin + LaunchPadding
(75, in DIPs so it scales with DPI), clamped so the window is never pushed
off-screen. A window that fits stays wholly visible; one too big to fit falls
back to the work-area origin.
Size and maximized state are still persisted -- only position was dropped. The
size clamp is unchanged (saved values clamp to [MinWidth, work.Width], which is
why a saved 800x500 returns as 1366x768 per the XAML minimums).
The old clamp tolerated Left as low as work.Left - width + 120 and Top up to
work.Bottom - 80, ranges wide enough to leave the window almost entirely
off-screen while still looking like a successful clamp. A clamp that permits
the window to be unreachable is worse than none: it reads as a guarantee it
does not keep.
BroadcastPullOutTests is renamed ..._Window_Launches_TopLeft_... and now asserts
the constructor applies the derived placement for both an on-screen and a -99999
saved position. Placement math is covered by WindowPlacementTests as a pure
function needing no HWND.
