Research direction

Start in src/platform/linux/window_linux.cpp and inspect the Window::SetResizable(), SetSize(), and SetContentSize() paths alongside their GTK window handling. Review the linked window_manager issues for the described GTK behavior, then verify that disabling user resizing still allows programmatic size changes while preserving the intended fixed-size behavior.

Description

bug

Window::SetResizable() is a stub on Linux (src/platform/linux/window_linux.cpp), so setResizable(false) does nothing there.

Implementing it with gtk_window_set_resizable() runs into a known GTK behaviour: a non-resizable GtkWindow is sized from its default size or size request, so later SetSize() / SetContentSize() calls stop taking effect. The implementation needs to keep programmatic resizing working while the user can't resize. One option is to pin min = max size hints to the requested size instead of toggling resizable, or to update the default size together with the size.

Background, from window_manager (moving onto nativeapi in 0.6.0):

leanflutter/window_manager#522: setSize() ignored after setResizable(false) (also #238)
leanflutter/window_manager#523: a PR that added a Linux-only setDefaultSize to work around it
