ROOT COMPARISON HELPER — CORRECTED TYPE COMPARISON

The first run of tools/verify-and-package.cjs stopped at:
AssertionError [ERR_ASSERTION]: Artwork recovers original packet
  actual: Uint8Array(12499)
  expected: Buffer(12499) [Uint8Array]

The helper used assert.deepEqual on different typed-array classes. That checks
the object types as well as the bytes. The decoder returns Uint8Array, whereas
the filesystem reader returns Buffer. The helper was changed to compare byte
content with Buffer.from(decoded).equals(fileBytes), for both artworks.
No score, packet, image, grammar, dictionary or interpretation was modified.
The subsequent report records the byte comparisons and other results.
This was a development error in the added comparison helper, not an observed
corruption of the recovered artifact.
