Fire an event on showing "MCPHUB Confirmation" window

[powerman]

It's useful to have sound notifications when LLM waits for an input or sent a final answer. Second part is already possible with events sent by CodeComplete, but MCPHub confirmation window is currently shown without firing any user events which can be used to setup sound notifier. I suppose it's possible to work around this by using auto-approve callback, but didn't tried this yet, and, anyway, it'll be nice to have this feature without misusing auto-approve feature.

Yeah, the workaround works:

require('mcphub').setup {
    auto_approve = function(params)
            if vim.g.codecompanion_auto_tool_mode then
                return true -- Auto approve when CodeCompanion auto-tool mode is on.
            end
            if not params.is_auto_approved_in_server then
                vim.api.nvim_exec_autocmds('User', { pattern = 'MCPHubConfirmationNeeded' })
            end
            return params.is_auto_approved_in_server -- Respect servers.json configuration.
    end,
}

@powerman Thanks for the suggestion! 🎉

This has been implemented in commit 2218737. MCPHub now fires MCPHubApprovalWindowOpened and MCPHubApprovalWindowClosed events when showing confirmation dialogs.

You can now set up sound notifications like:

      vim.api.nvim_create_autocmd("User", {  
          pattern = "MCPHubApprovalWindowOpened",   
          callback = function()  
              vim.fn.system("paplay /path/to/notification.wav &")  
          end,  
      })
