Adds store_on_rom() helper (tmpfs $TMPDIR + squashfs/ubifs/overlay $BINDIR). On such devices core_webget no longer downloads the upx core (its stub decompresses into a memfd = RAM at runtime); it fetches the tar.gz instead and core_check stores the naked binary as $BINDIR/CrashCore.raw, symlinked from $TMPDIR. The binary is transparently compressed on rom and file-backed/reclaimable at runtime (RssShmem 0). Other filesystems and explicit upx keep prior behavior. Also corrects the upx branch symlink target $TMPDIR -> $BINDIR (same dangling-symlink issue as #1295). For #1304
