Searches the available bank connectors by name (pass keywords[], e.g. ['nubank','btg']) and returns, per match: the connector id, whether it's Open Finance or API (`access`), PF/PJ (`audience`), the user's already-linked connections (and accounts when include_accounts=true), and a ready `connect_url` with the bank pre-selected. Honors the user's plan (a PF plan hides PJ banks). Call this BEFORE connecting to hand the user a one-click link to the right bank. keywords[] is REQUIRED — without it returns a hint (never dumps the whole catalog).
