Revise the README

[haok1402]

1. Move "Model Compatibility and Evaluation" section into the fourth step for getting started, as evaluation is the natural next step after the training completes.
2. Revise the "Attribution" section to include the CMU FLAME center and DGX B200 from NVIDIA for providing us with the compute resources.
3. uv venv would prompt the user what to do if the virtual environment exists, so we can remove that separate line of comment for "skipping". It is the uv's responsiblity.

Code Review

This pull request updates the README.md to provide a more detailed and structured 'Getting Started' guide, covering dataset preparation, training configuration, and checkpoint export. It also updates the attribution section to acknowledge CMU, the FLAME Center, and NVIDIA. The review feedback suggests several improvements for better documentation clarity and consistency, including adding trailing slashes to directory links, providing direct links to configuration files, refining the description of the export step, and ensuring the attribution to original sources remains complete.

Is this intentional?

[haok1402]

@MasterJH5574 Good catch. I just want to remove that in-line comment with uv venv. Fixed.

[MasterJH5574]

Ah no I mean the comment was added intentionally, since when there is already an existing environment, running uv venv will reset that environment.

[haok1402]

Got it ; I've reverted this line to keep the comment.

Okay thank you!
