/**
 * RFC-063r §2.2: factory that builds a {@link ChatOrigin} for a cron-triggered
 * agent invocation. Lives in {@code vip.mate.cron} so the dependency arrow
 * points {@code cron → agent} only — symmetric with
 * {@code ChannelChatOriginFactory} in {@code vip.mate.channel}.
 *
 * <p>workspaceId is reverse-resolved from {@code agent.workspaceId} (with the
 * legacy {@code 1L} fallback to keep behavior identical to
 * {@code CronJobService.executeJob}). workspaceBasePath is intentionally not
 * persisted — the value is derived at run time from the agent's workspace
 * configuration, matching the previous {@code ToolExecutionContext.workspaceBasePath()}
 * semantics.
