3.2 Window snapping and tiling: drag-to-edge halves, corner quarters, top maximize #102
Description
Goal
NEXT.md step 3.2 (Phase 3, Zack's lane). Design: Aero-style snap zones during WindowFrame drag - left/right edge = half, top edge = maximize, top/bottom corners = quarter; translucent preview overlay (fixed, pointer-events-none) while a zone is active; release applies the snap; a subsequent drag away from the snapped position restores the pre-snap rect. os.ts gains an explicit setWindowRect/snap action (store currently has no resize); pre-snap geometry rides on the OsWindow record. Workspaces are NOT in this issue (one purpose per PR) - will be split. Phone widths excluded (drag disabled by 3.1).
Done when
- dragging a window to the left or right edge shows a preview and on release tiles it to that half
- dragging to a top/bottom corner tiles a quarter
- dragging to the top edge maximizes
- dragging away restores the pre-snap geometry
- multi-desktop workspaces are split to their own issue
- e2e covers snap left and restore
- desktop-only (drag is disabled below 768px per 3.1)

Windows-style unsnap per review: title bar keeps its grab spot under the pointer, movement-delta skipped on restore move, maximized preSnap geometry sanity (y:0/real width), spec guards assert pointer-in-header after drag-away. typecheck/build 0, e2e 6/6. Commit 3f27ada.
