Establishes version control practices for all Firefrost repositories:
- Conventional Commits format (feat, fix, docs, etc.)
- Commit message structure (type, scope, subject, body, footer)
- Chronicler attribution requirements
- Git identity configuration
- When to commit guidelines
- Versioning practices for standards and code
- Commit checklist
This standard was referenced in Project Instructions but never
existed until now. Fills the gap in our standards library.
