New file: test/domains/continuum/test_reset_functions.jl Tests for: - reset!(cache) for COOCache - Validates counter reset to 0 - Validates I, J, V arrays zeroed - Validates force vector zeroed - Validates element/geometry/material caches reset Purpose: - Ensure caches can be reused across multiple assemblies - Verify no stale data remains - Test incremental assembly workflows Critical for iterative solvers and nonlinear problems where assembly is repeated many times with updated state.
