Subject: [PATCH] test(continuum): Add tests for dofs_per_node function
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

New file: test/domains/continuum/test_dofs_per_node.jl

Tests for:
- dofs_per_node(field) for various field types
- Displacement{3} → 3 DOFs per node
- Temperature → 1 DOF per node
- DisplacementRotation → 6 DOFs per node (future)

Validates correct DOF count for field types used in
DOF mapping and cache dimensioning.
