AP => AT: Generated link preview causes link to original post to be omitted in truncated posts.

Example: https://bsky.app/profile/kelson.notes.kvibber.com.ap.brid.gy/post/3lc7f5ngdf5d2

Most likely a regression due to #1411.

There are two options here, I think:

a) Don't generate a link preview, use the attachment to link to the original post.
a) Put the link to the original post as fragment onto the "[…]" at the end of the post.

Ugh yes, exactly right on all counts, thanks for raising.

Looks like this post was bridged by the first, buggy deploy of this feature, and the final deploy doesn't have this bug. Phew! Example: https://bsky.app/profile/fedi.test.snarfed.org/post/3lcbyl35456e2
