Keep line breaks in values, handle scalar and string-array JSON

Browse Source 
- esc() helper escapes free-text values and converts newlines to <br>;
  used for commit messages, SMS text, annotations, and all JSON values
- JSON parser accepts scalar bodies (string, number, bool, null) and
  renders them as a one-row table instead of falling back to the
  default template
- Arrays of plain values render as one table under their path
  breadcrumb, so nested string lists are no longer anonymous
- GitHub commits render as cards with a sha pill linked to the commit
