xVeil v0.13.40

[0.13.40] — 2026-09-03

Fixed

• A native build on an ARM64 Windows machine now works without being told a
  secret. BoringSSL has no assembly route for Windows on ARM64, and the crate
  that knows the answer cannot reach it on a native build; the release
  workflow has handed over the toolchain file that says so since v0.13.11, but
  nothing handed it to a person running the builder by hand. The build died
  deep inside cmake with a message naming no cause. The builder sets it itself
  on an ARM64 Windows host, and refuses loudly if the file is missing.

Changed

• veil 0.11.18: two Windows CI test steps were running zero tests, and audio
  playout now reports whether it actually started.
