docs/v322_new.md exec/load/filecontents_lib.js exec/webfileindex.ssjs Log Message:
View self-extracting .exe archives in the web file index

libarchive already reads the Zip or 7-Zip payload inside an SFX stub --
it locates the archive's signature rather than insisting the file start
with one -- so nothing but an extension gate stood in the way. Verified against both a 7-Zip SFX and an .exe with a Zip appended; a plain
program still fails to extract and is stored as the negative verdict it
is.

webfileindex.ssjs kept its own list of archive extensions, a shorter one
than the library's, so 'arj', 'zoo', 'tar', 'gz' and 'bz2' were listable
but never offered. It now asks contents.is_archive(), leaving one list
to maintain, and 'exe' is added to it.

extract_external(): an empty lsarContents with a non-zero lsarError is a failure rather than an empty archive. lsar recognizes a self-extracting
Zip whose stub offsets it won't follow and says exactly that; storing it
as a zero-entry listing misreported the file (043587351c9).
