Refresh roast.md to acknowledge recent progress

[jesusvilela]

Motivation

• Update the repository roast to acknowledge recent progress while keeping a sharp, actionable critique.
• Help maintainers prioritize hygiene, reproducibility, results traceability, documentation, and code quality improvements.
• Replace the older, more fragmented critique with a single, easier-to-follow overview aimed at operational fixes.
• Provide concrete next steps so future contributors can quickly orient and reproduce work.

Description

• Replace the contents of roast.md with a "Post-Progress Edition" that recognizes improvements and highlights remaining issues.
• Reorganize the roast into focused sections: Structure & Hygiene, Reproducibility, Results & Evaluation, Documentation, Code Quality, and Final Verdict.
• Add concrete recommendations such as consolidating artifacts into results/ and analysis/, creating docs/ and scripts/, and offering a single golden-path entrypoint via make or python -m.
• Suggest operational conventions including pinned dependencies and standardized output naming like {experiment}/{seed}/{metric}.json for traceability.

Testing

• No automated tests were executed for this change.
• The change is documentation-only and does not modify functional source code or test suites.
• Manual inspection of roast.md was performed to verify content and formatting.
• The PR was created without running CI or lint/test jobs.
