/**
 * List workspace audit events (`GET /v1/audit`): sign-ins, sharing, member changes, API and MCP
 * access, and more, newest-collected first, with actor and request context.
 * Needs an Audit API key (Enterprise; admin creates it in Settings → Connectors → Audit API keys; https://docs.granola.ai/audit).
 * Personal and workspace API keys get 404. Events cover the last year. Action catalogue: https://docs.granola.ai/audit-events
 *
 * @param input.account - Account name (secret `granola-<account>`). Required. @param input.secretName - Secret override.
 * @param input.action - Exact action or dotted prefix, lowercase (`workspace` matches `workspace.member_added`).
 * @param input.occurredAfter - `YYYY-MM-DD` or ISO date-time (within the last year). @param input.occurredBefore - same.
 * @param input.limit - Max events (1-5000, default 100). @param input.paginate - Follow cursors (default true). @param input.cursor - Resume.
 * @returns `{ account, count, events: [{ id, action, occurred_at, collected_at, actor, data, context }], hasMore, cursor }`
 *
 * @example
 * import listAudit from 'kody:@charlesmatte/granola/audit/list'
 *
 * const logins = await listAudit({ account: 'work-admin', action: 'auth', occurredAfter: '2026-09-01' })
