+Added new functions to the `@biomejs/wasm-*` packages:
+- `fileExists`: returns whether the input file exists in the workspace.
+- `isPathIgnored`: returns whether the input path is ignored.
+- `updateModuleGraph`: updates the internal module graph of the input path.
+- `getModuleGraph`: it returns a serialized version of the internal module graph.
