Closes #220
Float / // % and impure + - * on numpy-element values compile with numpy scalar semantics (divmod port, inf/nan on division by zero); pure functions deopt on an FP exception so the interpreter warns; impure functions emit numpy's RuntimeWarning text via PyErr_WarnExplicit with the real file, line and warningregistry. nbody advance/energy with NDArray params compile and match results, types and warnings. int64 element + - * // % in impure functions stays on the object path (conservative rule).
Red: 23 of 59 test_buffer_numpy.py failed before. Disabling the compiled warning emit fails 13 tests. Local 3.15t full suite: 1321 passed, 3 skipped. Benchmark compiled set identical to develop (benchmarks use lists, not numpy).
