Enhance the experience of using the kakehashi language server with Neovim.

kakehashi bridges other language servers, and configuring them twice — once for Neovim, once for kakehashi — would be a chore. inherit_nvim_lsp_config hands your vim.lsp.config definitions over to the server, so kakehashi serves the same language servers you already enabled:

vim.api.nvim_create_autocmd("LspAttach", {
  callback = function(ev)
    local client = vim.lsp.get_client_by_id(ev.data.client_id)
    if client and client.name == "kakehashi" then
      require("kakehashi").inherit_nvim_lsp_config(
        client,
        vim.tbl_keys(vim.lsp._enabled_configs),
        "keep"
      )
    end
  end,
})

The server parses documents with tree-sitter, so these work without installing tree-sitter parsers on the client:

• Conceal — require("kakehashi.extra.conceal").toggle() hides text the way the highlights queries direct (e.g. code-span backticks in markdown).
• Sticky context headers — require("kakehashi.extra.context").toggle() pins the headers of enclosing functions/classes/sections at the top of the window, like nvim-treesitter-context.
• Context-aware 'commentstring' — require("kakehashi.extra.commentstring").get() answers -- %s inside a lua block of a markdown file and {/* %s */} inside JSX, like nvim-ts-context-commentstring. Queries bundled for 120+ languages, with a Comment.nvim recipe included.
• Endwise — require("kakehashi.extra.endwise").get() tells which closing keyword (end, fi, endif, ...) the construct at the cursor still needs, like nvim-treesitter-endwise.
• Queries and nodes — kakehashi.lsp.captures runs any query kind over the document (one-shot, incremental, or watched), and kakehashi.lsp.node inspects and navigates syntax nodes.

See :h kakehashi for the full reference, prerequisites, and recipes.
