Bootstrap repository as a paper-tracking scaffold (LaTeX + BibTeX + tracked PDF) and replace README with fill-in template

[Copilot]

This repo was intended to be a minimal paper workspace and revision log, but only had a placeholder README. This change establishes the expected artifact layout and converts the README into a reusable template for future paper updates.

• Paper artifact scaffold

  • Added main.tex as a minimal LaTeX entrypoint with title/author/abstract/intro placeholders.
  • Added references.bib with a starter BibTeX entry to make citation flow explicit.
  • Added main.pdf as the tracked compiled-paper placeholder artifact.

• README converted to boilerplate template

  • Replaced the one-line README with a fill-in template covering:
    • repo purpose and expected files
    • basic usage flow (edit tex, update bib, commit compiled pdf)
    • lightweight changelog section with date/summary placeholders
  • Kept repository context explicit (fcmp-grimoire, full-chain membership proofs).

• Template shape (example)

  \documentclass[11pt]{article}
  ...
  \bibliographystyle{plain}
  \bibliography{references}

Original prompt

This barebones repo is to hold a latex main file, a bibtex file, and the compiled pdf, and to act as a change log for future modifications to the paper. I want the readme to be a boilerplate template i can fill in myself.
