Moonlight: update scaling and distributed Muon training

Added weight decay and adjusted parameter-update scales for large-model Muon, implementing ZeRO-style distributed orthogonalization and releasing Moonlight checkpoints with scaling experiments.

What is recorded here?

Added weight decay and adjusted parameter-update scales for large-model Muon, implementing ZeRO-style distributed orthogonalization and releasing Moonlight checkpoints with scaling experiments.

Source-linked catalogue note. A detailed explanatory guide has not yet been prepared for this entry.

Scientific scope

Extends rather than invents Muon/NewtonSchulz/ZeRO, and differs from KimiK2 MuonClip. Approximately twofold compute efficiency is fitted/reported for studied training regimes, not universal wall-clock superiority or tuning-free performance for every architecture.
