 * Reads package (and R) versions from a pasted `sessionInfo()` output block within a source file (typically inside

 * like a lockfile. Detection is conservative: we only act once we see the `R version` line and/or one of
 * `sessionInfo()`'s package-listing headers, and additionally require at least one `pkg_version` token so unrelated
 * text is not misread.
