Dependencies

This feature depends on:

1. Branch strategy decision - affects release tagging workflow
2. Changelog workflow (Create changelog generation workflow #7) - release notes may come from changelog

No Major Blockers

This is a safe feature that doesn't require Snowflake credentials.
Can proceed once branch strategy is decided.
