glob/globSync returns host-separator paths on Windows. Nine scripts that consume these paths for split('/'), manifest-key comparison, startsWith/includes exclusion checks, or committed-output rendering now normalize with .map(s => s.split(sep).join('/')) at ingestion. This replaces the previous replaceAll('\\\\', '/') with an explicit, self-documenting OS-separator-to-POSIX conversion.
