"chore: fix C lint errors (issue #)".
- Reference this issue in the "Related Issues" section of the PR body as "resolves #".

Start with lib/node_modules/@stdlib/ndarray/base/assert/is-contiguous/src/main.c at the stdlib_ndarray_is_contiguous signature identified in workflow run 29132267579. Review the reported shape and strides constParameterPointer warnings, then run the C lint workflow or its local equivalent; done means the reported lint errors no longer occur.
