Run HF↔Megatron conversion through Megatron-Bridge's multi-GPU converter by default so large checkpoints no longer need to materialize on one GPU. - add distributed torchrun command construction with tp/pp/ep/etp validation - support config-owned converter images/scripts while preserving env profile logistics - add Super-compatible tiny conversion configs for the 26.02 stack - document distributed conversion knobs and add focused runner/config-loader tests Signed-off-by: Rakesh Paul <rapaul@nvidia.com>

…ation Eliminate the `script.path` option from the documentation for both HF to Megatron and Megatron to HF conversion steps, as it is no longer necessary. This change simplifies the documentation and aligns it with the current implementation. Signed-off-by: Rakesh Paul <rapaul@nvidia.com>
- Renamed test functions for better readability and alignment with their purpose. - Removed unnecessary assertions and parameters to streamline tests. - Updated expected configuration values to reflect current implementation standards. Signed-off-by: Rakesh Paul <rapaul@nvidia.com>
