Pull request overview

Adds an addedDate timestamp to registry entries (extensions/themes) to record the UTC hour when an entry was first checked into the registry, and updates build tooling + schemas so the field is validated and automatically stamped when missing.

Changes:

• Add addedDate to all current theme/extension source entries and to index.json.
• Update JSON schemas (theme/extension/index) to validate addedDate as an hourly UTC ISO timestamp.
• Extend the registry stamping logic + tests so addedDate is set on first submission and preserved on updates.
