app.standard-reader.graph.mute

Mutes a subject for this reader: either a user (a DID) or a publication (the AT-URI of its site.standard.publication record). Presence of the record means muted; deleting it unmutes. The rkey is derived from the subject so each subject maps to a single record. Muted subjects are hidden from the reader's feeds and discovery surfaces, but direct navigation still works and subscriptions are untouched.
