Henrik RydgårdandClaude Opus 5.5 864778a11b FileSystems: Reject parent directory references in savestate file names ...

DirectoryFileSystem reopens the open files' guest paths on load, with
their original access mode, so a crafted state could create or truncate
host files outside the memstick or game folder. VirtualDiscFileSystem had
the same problem for reads. Guest paths never contain ".." here, the meta
file system resolves them.
