#164: ARIA-Semantik — Editorfläche, Autocomplete-Listboxen, Sidebar, Toolbar

Die Editorfläche bekommt einen lokalisierten zugänglichen Namen und ist
im Lesemodus role=document statt eines unbenannten Textfelds (setOptions
im selben Layout-Effekt wie setEditable). Eingeklappte Sidebar zusätzlich
inert (aria-hidden allein ließ fokussierbare Kinder im Tab-Weg). Die
li-Zwischenknoten der Listboxen (Wikilink-/Mention-Autocomplete,
Suchergebnisse) sind role=presentation, damit listbox→option wieder eine
gültige Eltern-Kind-Beziehung ist. Toolbar: Pfeiltasten-Navigation über
die Controls (native Selects behalten ihre Pfeiltasten) und ein
sprechendes Toolbar-Label statt des Absatz-Buttons-Labels.
