Module source 

doiget source <ref> — download an arXiv submission’s source bundle (every file) or just its figures to a directory (ADR-0034, issue #343).

Fetches the same arXiv source tarball as doiget tex-source (export.arxiv.org/src/<id>, one request) but, instead of extracting only the main .tex text, materialises files to --out:

• default: the full bundle (*.tex, *.bib, *.sty, figures, …),
• --figures-only: just the image artifacts.

Files are written opaque (never interpreted; ADR-0034 D2). Tar entry paths are sanitised in the core (sanitize_entry_path, ADR-0034 D3) and the join under --out is re-checked here as defence-in-depth, so a malicious archive cannot write outside the output directory (zip-slip).

• arXiv id → files under --out.
• DOI → NO_OA_AVAILABLE (pass the arXiv id).
• PDF-only / single-file / figure-less submission → TEXT_UNAVAILABLE (wire) with an actionable doiget fetch note.

--mode json emits {ok, arxiv_id, out_dir, figures_only, count, files[]}.
