Fix remeshing of open meshes (#2672) - #2675

Conversation
ACVD's ForceManifold treats clusters on an open boundary as non-manifold and keeps splitting them, piling extra vertices and sliver triangles along the boundary. With a cutting plane, geodesics and remesh percent < 100, the clipped mesh used for geodesics got these slivers, and particles clumped along the cut. Only force manifold output on closed meshes; regenerate the remeshPercent baselines.
