 *   - CLAUDE_CONFIG_DIR set externally → user is in a profile, don't override
 *   - resolver returns null → no opinion, caller proceeds with active
 *   - target email == active → resolver matched the active, silent
 *   - target email not saved → defensive guard (resolver should already
 *     have filtered, but listing can race with this read in pathological
 *     cases)
 *   - target has `defaultIsolated: true` → emit hint, do NOT flip
