attachments and /editor

[Schniz]

how do we see support for attachments and /editor?
even if an editor can't define an attachment (which I think it should be able to), we need to ensure that editing a prompt with the editor won't clear the attachments.

I see the following solutions:

1. /editor isn't supported when there are attachments (sounds like a no go)
2. /editor will get some markdown compatible for attachments and will get parsed upon save

I think that if we use bare markdown links it can be fire as llms.txt already use markdown links.

We can use [inline-links](./inline-links.md) or we would use the short which is neat too: [1] 

[1]: packages/opencode/index.ts

but in any case, links could be a neat syntax highlightable solution for this.
