xlogfiles — one line per game

Every game ever recorded, key=value per line. Under 100 MB for the lot. Split by server era — the directory the file lived in, not the NetHack version, which differs because binaries get upgraded under a running server. Read the version= field, not the filename.

The *dev* files are development-branch servers, kept here for completeness. Their games are excluded from NAO statistics, and they report the same version= as the release files — so only the filename tells them apart.

altorg-xlogfile-manifest.txt — game counts, date ranges, versions and checksums.
