Operating system/version

MacOS Mojave

Describe the bug

When sending a prompt, some buffers such as terminal buffers are not listed/available to be sent to a sidekick instance. It would be good to be able to send terminal logs and outputs alongside a prompt.

Steps To Reproduce

1. Open a terminal buffer.
2. Send a prompt and select buffers to send with the prompt.

Expected Behavior

Should send the last terminal output limited to.a certain number of characters to avoid overloading the context window alongside the prompt.

Repro

vim.env.LAZY_STDPATH = ".repro"
load(vim.fn.system("curl -s https://raw.githubusercontent.com/folke/lazy.nvim/main/bootstrap.lua"))()

require("lazy.minit").repro({
  spec = {
    { "folke/sidekick.nvim", opts = {} },
    -- add any other plugins here
  },
})
