wf_agent_profile already carried viewer.following (a repo record URI, mirroring how a follow is undone) but not blocking (the same shape) or muted (a plain account-level flag with no record to point at, since muteActor/unmuteActor have no output). A consumer showing mute/block state next to a fetched profile -- Cobalt's profile screen, in particular -- had no way to read either back. Parsed the same way viewer.following already is, in wf_agent_profile_from_response; freed the same way in wf_agent_profile_reset. Tested against both a viewer object carrying all three fields and an empty one, so absent state isn't fabricated as present.
