Mechanical, whole-tree `ruff format` pass — no behaviour change. Recorded in .git-blame-ignore-revs (next commit) so git blame skips it.

"""plex library HU-overlay columns (E5 S5a)
|
|
|
|
Adds `metadata_lang` (default 'en') and a self-referential `overlay_of` to plex_libraries. An
|
|
OVERLAY library is the Hungarian-metadata twin of another section: it is never browsed on its own —
|
|
its titles' HU fields are written onto the matched EN rows (paired by `guid`, see 0064). Cheap:
|
|
metadata-only, no table rewrite.
