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.

// styleTables used to substring + parse/hash + write .spellingState for
|
|
// EVERY table in the document per keystroke. Now a table only does that
|
|
// work when it renders (inactive + in scope) or shares a length with a
|
|
// rendering table (duplicate-sourceID stability). Typing prose renders no
|
|
// table → all skip. Table sources here are unique so they never warm the
|
|
// shared image cache used by TableImageCacheTests.
