Complete VEL interface package traceability metadata and verification vectors

[Copilot]

This updates the example VEL interface package so the collection/normalization artifacts are fully self-consistent: schemas remain the contract, the collector references the expected artifacts, and the normalization package now makes traceability metadata explicit and verifiable.

• Normalization metadata completeness

  • Added explicit normalization defaults for required output metadata:
    • time.clockDomain
    • traceability.inputSchemaVersion
    • traceability.normalizationRuleVersion
  • This closes the gap between the normalization rule and the normalized evidence schema requirements.

• Verification vector coverage

  • Added a focused normalization test vector that asserts:
    • unit conversion output
    • quality defaults
    • traceability fields
    • source message propagation

• Package integrity alignment

  • Refreshed signatures/content-digests.yaml so the integrity manifest matches the current package contents.

• Files updated

  • interfaces/vendor-a-npu-evidence-layer-package/mappings/vendor-a-npu-to-evidence-v3.1.0.yaml
  • interfaces/vendor-a-npu-evidence-layer-package/tests/normalization-vectors.yaml
  • interfaces/vendor-a-npu-evidence-layer-package/signatures/content-digests.yaml

Example of the added normalization defaults:

defaults:
  evidenceDomain: accelerator
  quality: {validity: valid, freshness: current, completeness: complete, mappingQuality: exact}
  time: {clockDomain: monotonic}
  traceability: {inputSchemaVersion: "1.2.0", normalizationRuleVersion: "3.1.0"}

@copilot content-digests.yaml change is duplicated with #31. We don't need it here.

Removed the duplicate digest update in daec6fb.
