Most archive attachments never had their images imported. The re-extract
action skipped archives without a post, and nothing kept game builds out
of an extraction.
- An archive holding executables, libraries, or game-engine data
(Ren'Py, Unity, Godot, RPG Maker, Python builds) is kept as an
attachment and not extracted. The same holds for one nested inside an
art pack.
- Re-extract now reaches archives imported from a folder without a post.
Their images go to the artist, in a folder named after the archive.
- Re-extract passes over archives whose members are already recorded.
- Re-extract stages each archive by symlink instead of copying it.
- The card says what the action does now.

Patreon attachment downloads land with sanitized URL-blob filenames
(01_https___www.patreon.com_media-u_v3_<id>) whose Path.suffix is junk, never
.zip — so the extension-only is_archive() filed them as opaque PostAttachments
and never extracted them ("No images attached to this post").
Add archive_extractor.detect_archive_format() — extension first, then magic-byte
sniff (zipfile.is_zipfile + RAR/7z signatures). is_archive(), extract_archive(),
and safe_probe._inspect_archive() (the bomb-guard) all route through it, so a
mis-named/extension-less archive is now detected, bomb-guarded, integrity-tested,
AND extracted regardless of filename. Stops new ones; part 2 re-extracts the
already-imported backlog.
Tests: mis-named zip detected + extracted; non-archive dotted name not
misdetected; _inspect_archive on a mis-named zip; signature updated.
