bug: duplicated input container window and confusing window sizes

[nfwyst]

Describe the bug

There is duplicated input container window created after splitting vertical terminal panel. and the sidebar width and the window layout messed up.

To reproduce

1. open neovim editor and open avante sidebar
2. focus on avante input container
3. add vertical panel for terminal(for example use zellij) which lead to vim resized

Expected behavior

1. the height of input container and selected file container, response container should recovery its original height
2. the width of sidebar should recovery its original width after closing vertical terminal panel
3. the token count should not overflow

Installation method

Use lazy.nvim/lazyvim:

local function switch_prompt(config)
  return function()
    local default_prompt = "你是一位出色的编程专家。"
    local prompt = default_prompt
    local msg = "prompt set to default"
    if config.options.system_prompt == default_prompt then
      msg = "prompt set to expert"
      prompt = PROMPT
    else
      prompt = default_prompt
    end
    config.override({ system_prompt = prompt })
    NOTIFY(msg, levels.INFO)
  end
end

local function init(config)
  CMD("TogglePrompt", switch_prompt(config), { desc = "Toggle Prompt" })
  config.override({ system_prompt = PROMPT })
end

local mode = { "n", "v" }
