Subject: Indicate `u-uid` as `rel=canonical`

This only displays on top-level entries, not ones in feeds. This
should help search indexers know which URI is the canonical for a
given link.

I wonder why Google doesn't bother to parse MF2 markup. Do they think
themselves monarchs of the Internet, able to show peasants their
place? their search results are shitty anyway, I'd rather ask
GPT-2. Yes, GPT TWO. Not even 3, 4 or 4o!
