Round 2's tag-name check on close popping fixed misattribution but could wedge the stack permanently: a mismatch with a real, still-open ancestor (e.g. an unclosed <p> before a later </div>, a normal optional-end-tag slip) never drained, so everything after it inherited the stuck depth and could print out of source order. Close handling now searches the whole stack for a matching tag, not just the top; frames above a found match are popped and implicitly closed (no fabricated close tag, just ending their indentation) before the match itself closes normally. A close with no match anywhere is still left in place untouched, since it has nothing to pair with. Also fixes a related idempotency bug in text-run whitespace collapsing surfaced while verifying this: boundary whitespace containing a newline (formatter-introduced structural gap) is now dropped entirely instead of being collapsed to a preserved space like same-line boundary spaces are.
