fix: Window menu tiling items are disabled - #413

Conversation
AppKit validates Fill, Center, Move & Resize, Full Screen Tile and Move to Display against NSWindow.isMovable. The main window set it to false to stop clicks under the transparent titlebar from becoming native drags; that is now handled by MainWindowHostingView returning false from mouseDownCanMoveWindow, the same approach upstream Ghostty uses.

#429) * fix: stop clicks in the main window from starting a native window drag Since #413 made the main window movable, a drag on the sidebar resizer band moved the window instead of resizing the sidebar. Keep the main window immovable while AppKit dispatches each left mouse-down, the same way the folder-icon guard already did, and restore it afterwards so the Window menu tiling items still validate. * test: deliver the movability click through a shown key window An unshown window dropped the synthetic mouse-down before hit-testing, so the recorder never saw it, and NSHostingView does not route clicks to raw AppKit subviews. Show the window and host the recorder via NSViewRepresentable.

What this does
The Window menu's Fill, Center, Move & Resize, Full Screen Tile and Move to Display items (and their shortcuts) are greyed out in Programa. This makes them work again.
Summary
macOS enables those items only when the window reports
isMovable == true. The main window was created withisMovable = false(from the cmux-era titlebar drag fix, and re-asserted in the chrome configure pass), which disables the whole tiling family. The flag was off to stop clicks under the transparent titlebar from turning into native window drags; that is now handled byMainWindowHostingViewreturningfalsefrommouseDownCanMoveWindow, the same approach upstream Ghostty uses with itsNonDraggableHostingView.isMovableByWindowBackgroundstays off, and the explicitperformDragpaths are unchanged.Test plan
