fix(state): read jq-pretty-printed array values from the state file

get_state_value() matched with a single-line sed that broke on the
jq-pretty-printed state file, where array values span multiple lines and
`[...]` never matched. Flatten the state (newlines/tabs -> spaces) before
matching, then:
- array values are returned as one-line JSON with element quotes intact,
  so callers can test membership against the exact quoted element;
- scalar values stay unquoted as before.
