Delete the old standalone COO assembler test now replaced by targeted coverage
under `test/assemblers/`.
- Drop `test/assemblers/test_dof_based_coo.jl`.
Remove legacy assembler cross-check tests superseded by the DOF-based zero-alloc
regressions and modern assembler modules.
- Delete `test/assemblers/test_assembler_equivalence.jl`.
