testament-burn: Add build/ compilation pipeline with Makefile, metadata, front/back matter
- build/build.py: Clean compilation script (md, epub, pdf via xelatex)
- build/metadata.yaml: Pandoc metadata (fonts, page size, formatting)
- build/frontmatter.md: Enhanced front matter with chapter guide table
- build/backmatter.md: Acknowledgments, sovereignty note, author bio
- Makefile: make all/pdf/epub/md/clean targets
- Updated .gitignore for build artifacts
Verified: markdown (19,490 words) and EPUB (213 KB) build successfully.
