Describe the problem

Related to #125 (comment).

The second instance fails when I start multiple language servers in the workspace.

I am going to close it as invalid.

The client must handle the command ID collision if they want to support a multi-LS setup.

For example, remap the command-id to $sketchUri:command-id with an LSP middleware.
