[FEATURE]:Content related to `opencode2 web` needs to be added to the `opencode2` doc

Feature hasn't been suggested before.

• I have verified this feature I'm about to request hasn't been suggested before.

Describe the enhancement you want to request

• Content related to opencode2 web needs to be added to the opencode2 doc.
• The page https://opencode.ai/v2/docs doesn't seem to mention opencode2 web at all. If there were documentation for opencode2 web similar to the opencode documentation at https://opencode.ai/docs/zh-cn/web/ , it would certainly help in understanding the details.
• If I do this,

npm install --global npm@latest
npm install --global --allow-scripts=@opencode-ai/cli @opencode-ai/cli@next
opencode2 web

• An error will occur.
