The double-quoted decoder appended real line breaks and continuation-line
indentation verbatim, so a multi-line "..." scalar kept its raw newlines
and leading whitespace instead of folding. It now applies YAML flow
folding at each unescaped break: a single break folds to a space, a blank
line to one newline, and whitespace adjacent to a break (the line's
trailing, the next line's leading) is stripped. First-line leading and
last-line trailing whitespace stay (they sit next to a quote, not a
break), and \n escapes are still decoded to literal newlines.
Measured against the official YAML test-suite, value-level conformance
rises from 135/169 (79.9%) to 143/169 (84.6%) with no regression.
Parse-level is unchanged: these documents already parsed, just to the
wrong tree, which only the value-level metric exposes.
