1.8.0 — Profile Statistics (gamut volume + B2A round-trip)

A new Profile Statistics section at the top of the Analysis tab reports, per
rendering intent:

  • Gamut volume (ΔE³) enclosed by the device→PCS transform.
  • B2A round-trip accuracy — ΔE*ab of a Lab → device → Lab round trip through
    the profile, as mean · P90 · max.

Built on two new IccProfLib-based iccviz metrics (GamutVolume, RoundTripDE).
Numbers are decimal-aligned; computed lazily and cached per profile. Algorithm
