retry tsdown migration build to survive qemu-user futex hangs

Browse Source 
Cross-arch arm64-on-amd64 docker buildx runs the rolldown-backed tsdown
build under qemu-user, whose futex emulation occasionally deadlocks the
worker threads. Wrap the call in a bounded timeout + 3-attempt retry so
a hang fails the layer in <11min and recovers on the next try.
