v0.68.0

Fixed

• addToCart no longer collapses an add into the quantity of an existing
  attachment-less line for the same SKU when the new item carries assembly
  options (e.g. B2B quoteData). The resolver now sets the per-item
  forceNewEntry flag (introduced by CHK-5575 in the checkout REST engine)
  on items that carry options, instructing the engine to bypass both its
  AddItemsAsync merge lookup and the pipeline MergeItems step so that
  the clean addItem produces a distinct line and the follow-up
  addAssemblyOptions attaches to it. Plain adds (no options) are
  unchanged.
