+/**
+ * Convert a CFG built from an EXTRACTED sub-document's AST (script-relative
+ * tree-sitter rows) into the enclosing file's coordinates by adding `offset` to
+ * every source-line field. Needed for embedded scripts — a Vue SFC `<script>`
+ * block parses at row 0 but lives at `lineOffset` in the `.vue` file, and every
+ * other worker-emitted graph node is already file-relative; without this, the
+ * CFG's `functionStartLine` would never join its Function/Method graph node
+ * (inter-procedural taint silently resolves nothing) and BasicBlock source
+ * lines would point at the wrong `.vue` line. A 0 offset returns the input
+ * unchanged (the common case: `.ts`/`.js`/etc. parse at the file root), keeping
+ * non-embedded languages byte-identical. Synthetic bindings keep `declLine` 0.
