Pull request overview

This PR expands the array constructors and conversion helpers in the three numpy-backed extension modules (qarray, qiarray, qcarray) to accept tuple shapes (multidimensional) and adds numpy-compatible copy/order/ndmin keyword arguments to array/asarray, plus an order keyword to ravel. Tests are added for the new shapes/keywords and for numpy reductions/concatenate/stack interoperability. A small fix in qcmplx.c adds float/int acceptance in PyObject_to_QuadCObject and corrects two bool-returning paths that wrongly returned NULL.

Changes:

• Add multidimensional shape parsing and shared ..._from_object / ..._parse_order helpers in qfloatarray.c, qiarray.c, qcarray.c; rewire array/asarray/ravel to use METH_VARARGS | METH_KEYWORDS with new kwargs; update .pyi stubs accordingly.
• In qcmplx.c, accept PyFloat/PyLong inputs in PyObject_to_QuadCObject and replace two return NULL; with return false; in a bool-returning function.
• Tooling: tighten build_and_test.sh with set -euo pipefail, and tweak .github/copilot-instructions.md wording (require limited API; ufunc preference; broaden test guidance). Tests added in tests/qarray_test.py, tests/qiarray_test.py, tests/qcarray_test.py.
