The ASan/UBSan and Valgrind shards intermittently have their hosted runner killed mid-run with "The runner has received a shutdown signal", surfaced as a mass test cancellation. The VM itself is being terminated, most likely from memory exhaustion: `-n $(nproc)+1` runs 5 parallel node-clusters and ASan roughly triples RSS, peaking past the 16GB hosted-runner ceiling on heavy shards (deterministic repro at ~10% on ASan/UBSan 3/6 due to the fixed --test-group-random-seed=42). Drop these two jobs to `-n $(nproc)` (one fewer worker) to lower peak memory, and add an `if: failure()` step that dumps OOM-related dmesg and kernel-log lines so the next failure records the actual cause.
