Paragraphs may disappear when editing AI generated transcript

我注意到 AI transcript 出來的文字
會有刪除一字之後 paragraph 就會爛掉的現象

paragraphs.mp4

我的直覺是
原本 AI 出來的文字單純以 \n 斷行
但 ProseMirror 要求以 <p> <br> 斷行
所以就會直接爛掉
老實講，我會希望 ProseMirror 可以是一個單純的文字編輯器更好
之後我頂多只會加上特殊符號的 syntax highlight 而已（例如約定 # 開頭的行爲註解，方便標記分區或 timestamp）之類

We should fix ProseMirror so that it acts as a text editor that does not have such paragraph problem.

Seems that a Prosemirror schema as simple as this

const schema = new Schema({
  nodes: {
    doc: {
      content: "text*",
      code: true,
    },
    text: {}
  }
})

Already covers all scenario we want.

We just need to handle the case for existing schema with multiple paragraph blocks. Maybe run a database migration to merge all paragraph blocks?
