…ab-i1

Add ZLab I1 segmented checkpointing support
…cumulation

Fix automatic oversubscription scheduling with gradient accumulation
fix(data): only restore a checkpointed shard when every rank has one
fix(data): keep post-split shard length when filtering a sample
Gate the shared prefetch-order write on is_local_main_process instead of
is_main_process, so the file also lands on node-local storage in
multi-node runs. Give the writer a process-unique temp filename so
concurrent node-mains on a shared filesystem cannot race on the rename.
(#2990 continued) LoRA state dict key naming cleanup
…-one

Fix checkpoint rotation after successful saves
