fix(release): prevent silent failures in version check and asset upload

- check-version: guard HEAD^ with git rev-parse so first commits
  in a repo don't crash the step
- build: set fail-fast: false so one OS failing doesn't cancel
  the others mid-flight; simplify condition to version_changed
  since force already flows into that output
- release: gate explicitly on version_changed
- release: abort if VERSION is empty instead of silently
  creating a bad tag
- release: abort if no artifacts were found instead of
  "succeeding" with an empty release
- release: fix asset upload using "$f#$dir" instead of the
  invalid --name flag, which was the actual cause of assets
  not landing
- release: track per-file upload failures and exit 1 if any
  upload fails, instead of silently succeeding
