- Synchronize Y.Js clients by AST (implements #8237).
- Before committing an edit, insert any parentheses-nodes needed for the concrete syntax to reflect tree structure (fixes#8884).
- Move `externalId` and all node metadata into a Y.Map owned by each `Ast`. This allows including metadata changes in an edit, enables Y.Js merging of changes to different metadata fields, and will enable the use of Y.Js objects in metadata. (Implements #8804.)
### Important Notes
- Metadata is now set and retrieved through accessors on the `Ast` objects.
- Since some metadata edits need to take effect in real time (e.g. node dragging), new lower-overhead APIs (`commitDirect`, `skipTreeRepair`) are provided for careful use in certain cases.
- The client is now bundled as ESM.
- The build script cleans up git-untracked generated files in an outdated location, which fixes lint errors related to `src/generated` that may occur when switching branches.
Added bidirectional synchronization of module edits with language server. All document edits made by any of the Yjs peers are sent to language server to apply to the file. Any local file changes cause reload, which is synchronized back to Yjs by finding a diff.
# Important Notes
- Binary LS endpoint is not yet handled.
- The parsing of provided source is not entirely correct, as each line (including imports) is treated as node. The usage of actual enso AST for nodes is not yet implemented.
- Modifications to the graph state are not yet synchronized back to the language server.
