Add tags and mute words (#2968)

* Add bare minimum hashtags support (#2804)

* Add bare minimum hashtags support

As atproto/api already parses hashtags, this is as simple as hooking it
up like link segments.

This is "bare minimum" because:

- Opening hashtag "#foo" is actually just a search for "foo" right now
  to work around #2491.
- There is no integration in the composer. This hasn't stopped people
  from using hashtags already, and can be added later.
- This change itself only had to hook things up - thank you for having
  already put the hashtag parsing in place.
