fix(nx-infra-plugin): address PR review comments

- normalizeEol: also replace standalone CR (\r) for full EOL coverage
- vectormap buildData: add ensureTrailingNewline for consistency
  with buildUtilsVariant
- compress: fail loudly when terser produces no output instead of
  silently returning uncompressed content
