fix: support multiple bind_default_trigger calls

Previously trigger_action_name + trigger_widget_id were module-local
scalars, so the second bind_default_trigger call overwrote the first
(and reused the action name 'panel_toggle' so lib-core.input's binding
was also clobbered). Switched to a triggers array; each binding gets
a unique input action 'panel_toggle_<widget_id>' so multiple widgets
can be toggled by their own keys independently.
