Closes #602.

Problem

scripts/nvx.py package checked five fields in each Ubuntu artifact manifest, but raised the same Ubuntu artifact manifest does not match <artifact> message for any of them. That hid whether the artifact digest or the build-input digest differed, which slowed down triage of the Windows Package release failure behind #599.

Change

In _guest_release_inputs, compare each field against its expected value and report every mismatch:

• names the failing manifest file,
• names each mismatched field with the manifest value and the expected value,
• reports a missing field as missing,
• prints digests in full,
• keeps the existing Ubuntu artifact manifest does not match <artifact> prefix so log searches and existing tests still match.

Tests

• Tightened test_guest_release_inputs_reject_stale_ubuntu_artifacts to assert the message names artifact_sha256 and not input_sha256.
• Tightened test_guest_release_inputs_reject_stale_ubuntu_source_inputs to assert the message names input_sha256 and not artifact_sha256.
• Added test_guest_release_inputs_report_multiple_mismatches_and_missing_fields covering two mismatching fields and a missing field.

Validation

I couldn't run the suite locally (host Python is too old); the focused tests are:

python -m unittest -k guest_release_inputs scripts/test_nvx_tools.py
python -m ruff check scripts
python -m ruff format --check scripts
