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.

// Regression: smart-input interceptors suppress the typed keystroke and
|
|
// perform a different programmatic edit. The incremental wiki splice must
|
|
// see THAT edit's descriptor — with the suppressed keystroke's stale one it
|
|
// silently diverged the storage form (and the persisted file) from the
|
|
// display text.
