v2.4.8

Added

• export-imports workflow command to collect dashboard import envelopes from
  protocol output directories.
• promote workflow command support for regenerating i18n exports during
  promotion.
• Generated i18n schema and hash metadata support for stricter translation
  drift detection.

Changed

• Hardened i18n artifact handling so non-translatable writes preserve existing
  translation outputs and sidecars can be restored from full artifacts.
• Expanded workflow proposal documentation for larger protocol-info follow-up
  improvements.

Fixed

• Enforced dashboard and i18n artifact contracts in tests and schema checks.
• Improved logo asset normalization and version-store handling around generated
  artifacts.
