Summary: Syncs six landed Distributed Shampoo changes to the OSS mirror via `scripts/oss_sync.sh`: - Add scalar AdaGrad, RMSprop, and Adam preconditioners (D113343599). - Add opt-in dimension normalization for Shampoo factors (D115506679). - Warn before loading mismatched checkpoint configs (D119209553). - Fix lossless-distributor checkpoint resume with gradient-free parameters (D117916151). - Remove redundant Newton-Schulz tests that broke the isolated OSS suite (D117256061). - Document `NewtonSchulzRootInvConfig` in the preconditioner guide (D116595018). The mirror is generated by the sync script. The new `CHANGELOG.md` entry was rewritten by hand into public-facing release notes without internal references. The generator also re-listed D116658375 because the prior sync marker deliberately lagged that then-draft commit. Its code and release note already shipped in D116726514, and there is no corresponding hunk in this mirror diff, so the duplicate generated bullet is omitted. The last-sync marker advances to `e49b13980a27`, the landed D113343599 commit.
