The post-merge 26.6.1 dev release failed strict fileset validation with a
missing pypy311-win-amd64 wheel. Two defects:

1. build-all (justfile) swallowed per-interpreter build failures: a failing
   'just build <venv>' did not fail the recipe (no set -e; the loop ended in
   'ls'), so the Windows wheels job went green while silently omitting a wheel.
   Now build-all attempts all interpreters but exits non-zero if any failed,
   naming them - the same false-green class as crossbario#1856 / zlmdb#116.

2. The PyPy/Windows build aborted installing the core dependency cbor2: cbor2
   6.x is Rust/pyo3-only (no PyPy/Windows wheel, and the pure-Python fallback +
   CBOR2_BUILD_C_EXTENSION toggle were removed in the 6.0 rewrite), so pip built
   from sdist and the pyo3 link failed (unresolved PyPyModule_FromDefAndSpec2,
   a known pyo3-on-PyPy/Windows limitation). Cap cbor2 < 6 *only* on PyPy/Windows
   via environment markers - the 5.x line ships a pure-Python wheel and runs at
   near-native speed on PyPy - while keeping cbor2 6.x everywhere else.

PyPy/Windows is kept as a build target and a required release artifact; the
native NVX build is attempted there (it was never reached before, since cbor2
aborted first). If NVX itself turns out not to compile on PyPy/Windows, the
now-loud build-all will surface it and we retreat to excluding PyPy/Windows.

Note: This work was completed with AI assistance (Claude Code).
