gigapdf-lib v0.65.0

Added

• Office→PDF phase-2 fonts — officeToPdfWith(office, fonts) (ABI
  gp_office_to_pdf_with_fonts, core office_to_pdf_with_fonts) completes the
  two-phase font flow opened by officeNeededFonts: hand back the host-fetched
  faces for the families a container references but doesn't embed (e.g.
  Carlito for a Calibri reference) and styled runs lay out + paint with the right
  metrics instead of drifting onto the bundled fallback. The supplied faces are
  merged with whatever the document embeds itself — embedded faces win on
  conflict — so an empty fonts array yields exactly officeToPdf's output
  (no regression). fonts uses the same packed blob as htmlRender.
