Feature Request: Popup menu to select window tiling

Briefly describe how the feature should work
Users who likes to interact with the entire screen through mouse navigation can snap windows through monitor edges. Users who likes to manage window tiling through keybindings can also snap windows efficiently. But there are also users who would benefit with mouse snapping through popup menu specially if they have huge display.

Explain why this feature should be added
This feature should be added for pure ergonomics. Reducing the burden to drag windows in long distances just to select tiling allocation.

This is similar to Tiling shell but will be designed to feel more shell native

Two types of this will be added:

• Global drag and drop
• Local window menu where you can click preferred tiling allocation (unlikely)

Conceptual look:

No files or tests are named; start by reviewing Tiling Assistant’s existing mouse-edge snapping and keybinding tiling flows. Compare the proposed global drag-and-drop and local window-menu variants, then clarify which behavior and scope is required. Done criteria are not specified beyond selecting a preferred tiling allocation through mouse interaction.
