Prefer maximize on first Super+Up before tile navigation

[krscott]

Problem

When Tiling Shell move keybindings are enabled, pressing Super + Up on a tiled or partially tiled window first moves/snaps the window to another tile, and only a second Super + Up maximizes it.

This differs from vanilla GNOME behavior, where Super + Up maximizes the focused window directly. It also makes the common GNOME shortcut feel surprising when Tiling Shell is installed: the shortcut still looks like the normal maximize shortcut, but it now prioritizes tile navigation.

Expected behavior

There should be a way for Super + Up to maximize/full-screen the focused window on the first press, while still keeping Tiling Shell keyboard movement for left/right or for a separately configured up/down binding.

Possible solutions:

1. Add an option for move-window-up to prefer maximize before tile navigation when the binding is Super + Up.
2. Split the native override behavior so users can keep GNOME native maximize/unmaximize on Super + Up/Down while still using Tiling Shell movement on Super + Left/Right.
3. Do not clear GNOME native maximize/unmaximize if the Tiling Shell move-window-up/down bindings are unset or remapped elsewhere.

Actual behavior

With move keybindings enabled:

1. Focus a window that is tiled/snapped, for example to the left half.
2. Press Super + Up.
3. The window moves/snaps to a tile/section first.
4. Press Super + Up again.
5. The window maximizes only on the second press.

Why this seems to happen

In src/keybindings.ts, enabling move keybindings calls _overrideNatives(), which clears GNOME native keybindings for:

• org.gnome.desktop.wm.keybindings maximize
• org.gnome.desktop.wm.keybindings unmaximize
• org.gnome.mutter.keybindings toggle-tiled-left
• org.gnome.mutter.keybindings toggle-tiled-right

Then Tiling Shell registers move-window-up on Super + Up.

In src/components/tilingsystem/tilingManager.ts, onKeyboardMoveWindow() maximizes on UP only when the current assigned tile is already at y === 0, or when no destination tile is found. If a tile destination exists, tile movement wins before maximize.

Workaround limitations

Disabling Tiling Shell move keybindings restores vanilla GNOME Super + Up, but also disables the extension keyboard movement for the arrow keys.

Unsetting or remapping only move-window-up does not appear to be enough, because the native GNOME maximize keybinding is still cleared while move keybindings are enabled. This overlaps with #513, but the user-visible request here is specifically about preserving the vanilla maximize-first behavior for Super + Up.
