⚠️ Potential issue | 🟠 Major

Sync .main.commit with this new submodule SHA to avoid checkout drift.

Line 1 updates 3rdparty/Megatron-LM to 51ea688a..., but .main.commit is still pinned to ec458b67.... Since scripts/switch_mcore.sh reads .main.commit to switch submodule state, ./scripts/switch_mcore.sh main will now move users back to the old commit. Please update .main.commit in the same PR to keep tooling consistent.
