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.
