Função: initCloseButton()

initCloseButton(btn): void

Conecte um botão de fechar para descartar o elemento alvo.

Target resolution (first match wins):

1. data-close-target="id" — dismiss the element with that id
2. popovertarget / commandfor — skip; native browser handles it
3. walk up to the nearest <dialog>, [popover], or [data-dismissible]

Dismiss strategy:

• <dialog> → dialog.close()
• [popover] → el.hidePopover()
• [data-dismissible] or [open] → remove open attr + fire bubbling close
