On OpenWrt $TMPDIR is tmpfs (RAM) and $BINDIR sits on a transparently-compressed fs (squashfs/ubifs). Unpacking the core to $TMPDIR pins the whole ~40MB binary in unreclaimable Shmem, and a compressed copy is still kept on rom - paying twice. When $TMPDIR is tmpfs and $BINDIR is squashfs/ubifs/overlay, store the verified naked binary as $BINDIR/CrashCore.raw and symlink $TMPDIR/CrashCore to it, dropping the downloaded archive. The binary is transparently compressed on rom (~2.2:1, comparable to keeping .gz) and its text/rodata become file-backed and reclaimable at runtime (RssShmem 0). Other filesystems keep the existing behavior. The upx branch's symlink target is also corrected from $TMPDIR to $BINDIR (same dangling-symlink issue as #1295). For #1304
