### Release notes
- Fixed a bug with...
This adds the HTMLRewriter-based bookmark unfurler to the demo server.
It moves the unfurler into worker-shared, and adds some better shared
error handling across our workers.
I removed the fallback bookmark fetcher where we try and fetch websites
locally. This will almost never work, as it requires sites to set public
CORS.
### Change type
- [x] `other`
Adds an assets server to the demo worker, and reworks the existing asset
server to use the same code. There are a few simplifications to the code
due to some DX improvements working with R2 and caches. I also removed
the `HEAD` request from the assets server: i took a look at our logs and
it's not actually used at all.
This also fixes an issue where users could overwrite the contents of the
asset uploads bucket.

Sets up preview deploys etc. for bemo worker.
There's enough going on here that I wanted to make it its own PR. I'll
rework david's spike on top of it once it's landed.
