- 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- The build script cleans up git-untracked generated files in an outdated location, which fixes lint errors related to `src/generated` that may occur when switching branches.
Implements #8025: `LazyObject` now has a `visitChildren` method that observes each direct-child `LazyObject`. `childrenAstNodes` is now a simple function that flattens non-Tree nodes out of the hierarchy; `validateSpans` visits both `Tree`s and `Token`s the same way we would use the `ItemVisitor` Rust API.
Generate TS bindings and lazy deserialization for the parser types.
# Important Notes
- The new API is imported into `ffi.ts`, but not yet used.
- I have tested the generated code in isolation, but cannot commit tests as we are not currently able to load WASM modules when running in `vitest`.
- Depends on #7773.
- Implements binary WebSocket protocol (data protocol)
- Performs some editor initialization (the bare minimum so that visualizations work)
- Adds event handlers to receive visualization data updates
# Important Notes
None
# 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.
