Description#
Derives the shared sort-header state for one column from a CngxSort getter.
Both CngxSortHeader (table context, aria-sort) and CngxDgaSortHeader
(disclosure context, role="button" + aria-describedby) compose this factory
and keep only their own a11y presentation. The factory is a11y-agnostic - it
returns the plain derived signals each header maps to its own DOM/ARIA surface.

@paramsort
Getter for the owning CngxSort engine (() => sortRef, () => grid.sort).
@paramfield
Getter for the column's field key.
Returns#
SortHeaderState The derived { entry, isActive, isAsc, isDesc, priority, toggle } bundle.
