-- Warn when an AUR package's maintainer changes between upgrades.
--
-- The known maintainer for each package is stored in a plain text cache file
-- inside the yay cache directory (build_dir). On the first upgrade for a
-- package the current maintainer is recorded without any warning. On
-- subsequent upgrades:
-- * same maintainer → debug "match correct"
-- * different maintainer → error "new maintainer, double check build files"
--
-- The cache is updated whenever a new or changed maintainer is seen.
--
-- Cache file location: <cache_dir>/maintainer_cache
-- Format: one "pkgname=maintainer" entry per line.
-- missing reliable cfg getter
