Functions
G_BEGIN_DECLS void	dt_dev_history_gui_init (void)
	Install the history engine's GUI handlers. Called once from dt_init() beside the other handler installs – safe under ansel-cli too, because every handler fires only for a dev with a focused GUI module, which a headless dev never has.

Detailed Description

The GTK half of the history engine, following the blend.c/blend_gui.c pattern.

dev_history.c is the history ENGINE – item lifecycle, commit, replay, DB read/write, all under history_mutex discipline. What lives here is the part that touches widgets: the handlers the engine calls when presentation state rides along with an operation (undo records restoring the mask-edit view), installed once at GUI startup. With nothing installed – ansel-cli, a unit test – the engine skips the calls, which is what headless means.
