Subject: [PATCH] Only expose known-likers experiment when there's something to
 show

Fetch the likers sample for everyone signed in, then check the feature gate only if the viewer follows one of the likers. This keeps people who'd see no difference out of the test.

Note: this means app.bsky.feed.getLikes will be called on every thread page view for signed-in users for posts with at least 1 like
