Description
If we can enable --use-megatron-fsdp, we can save the GPUs from TP to CP and enable training longer sequences with the same number of GPUs. Currently it seems that we at least need to upgrade megatron for such feature.

Research direction
No files, tests, or entry points are named. Start by locating where the --use-megatron-fsdp option would be defined and how the current Megatron integration handles tensor and context parallelism; review the required Megatron upgrade. Done means the option enables FSDP training and longer sequences with the same GPU count, with coverage for the new path.
