001 runtime infinite loop

// Watchdog self-test (EXPECT_TIMEOUT): a koru program that infinite-loops at
// RUNTIME. The harness safety net (per-test process-group watchdog +
// inner binary timeout) must catch it and record a TIMEOUT failure instead of
// hanging the suite forever. With EXPECT_TIMEOUT, a CAUGHT hang = PASS.
