Fixes#8520
If the websocket is closed not by us, we automatically try to reconnect with it, and initialize the protocol again. **Restoring state (execution contexts, attached visualizations) is not part of this PR**.
It's a part of making IDE work after hibernation (or LS crash).
# Important Notes
It required somewhat heavy refactoring:
1. I decided to use an existing implementation of reconnecting websocket. Replaced (later discovered by me) our implementation.
2. The LanguageServer class now handles both reconnecting and re-initializing - that make usage of it simpler (no more `Promise<LanguageServer>` - each method will just wait for (re)connection and initialization.
3. The stuff in `net` src's module was partially moved to shared's counterpart (with tests). Merged `exponentialBackoff` implementations, which also brought me to
4. Rewriting LS client, so it returns Result instead of throwing, what is closer our desired state, and allows us using exponentialBackoff method without any wrappers.
When a node has an error/warning/panic that exactly matches one of its input nodes, hide the message until the node is interacted with, showing an icon.

# Important Notes
- New icon is used for panics.
- Opening circular menu now shifts any message out of the way, not just warnings.
Fixes#9313

# Important Notes
* This is PoC, so I didn't spend time on polishing the visuals; the design will likely change.
* I modified the shortcut handler a bit, allowing making multiple actions for same binding - the action's handler will be called in unspecified order, until one of them handle the event (i.e. not return false).
* To make it working regardless of imports, I needed to export AI module in Standard.Visualization. Moreover, needed to remove build_ai_prompt for Any, because it was causing issues - expect a bug report soon.
- Fix the UI problems with our CodeMirror integration (Fixed view stability; Fixed a focus bug; Fixed errors caused by diagnostics range exceptions; Fixed linter invalidation--see https://discuss.codemirror.net/t/problem-trying-to-force-linting/5823; Implemented edit-coalescing for performance).
- Introduce an algorithm for applying text edits to an AST. Compared to the GUI1 approach, the new algorithm supports deeper identity-stability for expressions (which is important for subexpression metadata and Y.Js sync), as well as reordered-subtree identification.
- Enable the code editor.
- 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.
