Closes#8680
The color picker is triggered by new Circular menu item or by keyboard shortcut (set to `Mod+Shift+C` for **C**olor).
The color picker affects *selected* nodes, so it works nicely both in cases when we use Circular menu on a single node a shortcut with multiple selected nodes.
Color is only changed when the user selects a new one inside the color picker, but there is no specific way to reset default color (you would have to recreate the node).

- Closes#8386
- Attempts to execute `<expr>.default_visualization` to query the engine for the *correct* fallback type
- If that is not possible, falls back to checking `inputType` - first for an exact match, then falling back to `Any` (i.e. the text/JSON visualization)
- Does not decide fallback based on the shape of the returned JSON
# Important Notes
Contains pretty significant refactors of `VisualizationMetadata` to allow it to be unset.
- 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
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.
