Subject: [PATCH] fix: skip sample MKVs during library collection

MKV library collection now filters out sample files before moving.
Files in "sample"/"samples" directories and files with "sample" in
their name are excluded. This prevents duplicate "(2)" entries in
the library folder caused by samples having the same base name as
the real episodes (just different casing from the archive).
