Convert from git submodule to plain vendored copy. No push access to upstream nodes-app/swift-markdown-engine meant our local fix commit (05c1720) was stranded and unreachable from any remote on fresh clones/CI. Vendoring as plain files folds it into normal repo history instead.

// The per-keystroke restyle hands its already-computed block list down to
|
|
// DocumentAST.parse so the styler consumes it verbatim instead of
|
|
// re-extracting + memcmp'ing the full document buffer every keystroke.
