A block sequence value carrying an inline property (`sequence: !!seq` then
`- entry` at the key's column) is a zero-indent sequence: its entries sit at the
mapping key's own indentation, so a following sibling key ends it.
The untagged form was already parsed as a zero-indent sequence that stops at a
sibling mapping key, but the property-bearing form fell through to the generic
node path, which parsed the sequence without that terminator and read the
sibling key as a mixed sequence-and-mapping entry. The zero-indent sequence is
now handled before the generic path, carrying any property to the sequence.
Fixes yaml-test-suite 57H4; raises parse-level conformance to 313/333 (94.0%)
and value-level to 206/206 (100.0%), with the should-error rate unchanged.
