What changed in this PR
This PR reduces backup I/O by streaming archive contents directly into sha256sum and quieting tar/gzip output.
Changes:
- Replaces per-file extraction with streaming checksum calculation.
- Removes verbose tar/gzip output.
- Appends generated checksums to the archive.
Two critical checksum-generation issues remain: hash failures can be masked, and escaped newlines can produce malformed checksum entries.
