Agent crash with Kate editor

[Mte90]

I just tried to setup the LSP server on the Kate kde editor with this settings:

"php": {
            "command": ["npx", "tabby-agent", "--lsp", "--stdio"],
            "path": ["/usr/local/bin"],
            "url": "https://tabby.tabbyml.com/"
        },
        "python": {
            "command": ["npx", "tabby-agent", "--lsp", "--stdio"],
            "path": ["/usr/local/bin"],
            "url": "https://tabby.tabbyml.com/"
        }

So now tabby is executed like the others.

Just created a php file and crashed with this error:

I think that the issue is on https://github.com/TabbyML/tabby/blob/main/clients/tabby-agent/src/protocol.ts#L100 and it is missing that capability.

It isn't better if the capabilities to avoid a crash and just report the error, like this capabilities is not supported yet?
