Loader Skill (clean version-numbered names)
Reads strings_v1.txt and strings_v2.txt in a loop, joins them, and eval()s the
joined result. This matches the sink (leg 1) and read-and-join shape (leg 2) of the
real chunked-file-loader detector, but the file names are ordinary version-numbered
assets -- they share a stem+extension differing only by a trailing digit, with no
explicit chunk/part marker word -- so the chunk-naming corroborator (leg 3) must not
fire.
