fix(api): filter raw responses with --jq and end output with a newline

tea api /version --jq .version failed with "--jq requires --json", and
--json is rejected for raw responses. api is annotated tea.rawjson now:
--jq filters each successful JSON response, page by page with
--paginate, and prints strings without quotes. A non-JSON response is
an error with --jq; an error response prints its body unfiltered.

JSON responses end with a newline, so an error no longer starts on the
line of the body; on a terminal JSON is indented and colored in the key
order of the response, and other text is sanitized as before. Piped
non-JSON bodies stay byte-exact.

api gains -i for --include and --silent, a Long help modeled on gh api
(placeholders, -f/-F typing, pagination, --jq) and examples, and its
help lists --jq.
