v0.5.2-alpha

Fixed

• Release workflow no longer tears down successful builds. A single failing matrix target used
  to run gh run cancel, which cancelled every other in-progress build and left the GitHub Release
  with no assets. That step is gone: with fail-fast: false each target now builds and uploads
  independently, so every target that does build still contributes its binary and checksum. The
  release job is also idempotent — it creates the release, or updates it when a partial run is
  re-run — instead of aborting because the release already exists.
