"""Verify the runtime packages are completely installed: every file each
package's wheel RECORD names must exist on disk. A top-level `import tinygrad`
passes on a partially extracted install (backends load lazily), and
importlib.metadata's `files` silently drops missing entries, so RECORD is
parsed directly here. Runs under the interpreter whose site-packages should be
checked; prints missing files and exits nonzero on any damage.
