Jannis Braun ba0f8637f5 docs(federation): document username on profile_update + new presence_update relay + stub backfill ...

- federation.md §10: extend FederationProfileUpdatePayload with username, document
  receiver fallback. Add Presence Sync sub-section: event shape, sender call sites,
  outbox-only (no mutation log) policy, peer-lifecycle hooks, flap recovery
  semantics. Add Stub Username Backfill sub-section + new
  /api/federation/users/by-home-id endpoint.

- activity-presence.md: resolve drift — line 147 previously claimed S2S
  presence_update relays existed but the code didn't ship them. Now points to
  federation.md §10 which describes the actually-implemented mechanism. Connect/
  Disconnect Flow updated to reflect collectProfileBroadcastTargetIds recipient
  set + S2S queueing.

- social.md / websocket.md: presence_update recipient column now reflects
  friends + DM + space co-members (matches user_updated), plus federated stub
  presence sourced via S2S.
