exact list names.
automations/remove-apollo-list-members.automation.ts
recordType is "contacts" | "accounts"; records and listNames are
non-empty arrays. Set async: true for background processing. Optional
account selects the Apollo binding. Returns { lists, job?, message? } with
the same synchronous/background semantics as addRecordsToList.
