Hybrid factory mapping ElementInfo.Type to a behavioral widget or the
UiDatElement generic fallback. Type 7 (UIElement_Meter) → UiMeter with
back/front 3-slice ids populated from grandchild image elements; Type 12
(style prototypes / BaseElement stores) → null so the importer skips
them; all other types → UiDatElement. Rect + anchors are set on every
returned widget via ElementReader.ToAnchors.
BuildMeter walks two levels of the element tree: the two Type-3 slice
containers ordered by ReadOrder (back behind, front on top), then within
each container the image children that carry a DirectState ("" key)
ordered by X for left-cap/center-tile/right-cap. The expand-detail
overlay (present in the front container with only named ShowDetail/
HideDetail states and no "" entry) is excluded by the TryGetValue("")
filter automatically — no name-matching needed.
Fill/Label providers are intentionally NOT set here; Task 6
(VitalsController) binds them to live stat data.
5 TDD tests: Type7→UiMeter, UnknownType→UiDatElement, Type12→null,
rect+anchors propagation, and meter slice extraction with overlay exclusion.
