Pull request overview

Adopts upstream changes (gismo PR #839) related to the new DoF mapper creation flow and related multipatch/C1 infrastructure updates.

Changes:

• Migrates many gsDofMapper(...) constructions to createMapper(..., dim, conforming) and adds the required includes.
• Adjusts element iteration to use beginAll()/endAll() in several C1 surface assemblers/gluing data paths.
• Updates several examples to match the new mapper creation and projection APIs; adds a degree precondition for AS-G1 construction.
