Emits one row per applicable recommendation: 'Create Introduction' when the viewer's local key (?__LOCALPUBKEY_multi) is in none of the user's introductions (localCount=0; carries the local-key bundle to prefill the create action), and 'Get approved' when the local key is in exactly one introduction that is not yet approved (localCount=1 and no loaded AccountState, checked by federating to the trust repo; carries the intro nanopub to link to). No rows for non-owners or logged-out viewers. local_pubkey/short/site_url are action-mapping data (hidden from display).";
