fix(release): correct artifact paths, add upload guard, dispatch to both taps

- Fix upload-assets paths: remove stale /dist/ subdir that upload-artifact@v7
  never creates (root cause of the v2.0.1 zero-asset release)
- Add explicit pre-upload file existence check that exits non-zero and dumps
  the artifact tree if any expected file is missing
- Add fail_on_unmatched_files: true to softprops/action-gh-release so glob
  misses are hard failures rather than silent no-ops
- Expand notify-homebrew to dispatch to both homebrew-amber_cli (underscore)
  and homebrew-amber-cli (hyphen) taps
