/**
 * Test: Cross-session memory should not trigger unprompted agent action
 *
 * This test verifies the fix for issue #1532:
 * - When a new session starts, auto-recall may inject memories from previous sessions
 * - The agent should treat these as background knowledge only
 * - The agent should NOT act unprompted based on cross-session memories
 * - The agent should wait for the user's explicit instruction
