Why

Generated apps should run without external setup, but teams should also be able to reuse proven GT patterns where useful.

This balances template usability with practical production readiness.

Acceptance Criteria

• A local/default config provider exists, so generated apps compile and run out of the box.
• A GT-informed remote config adapter can be plugged in without changing the Domain contracts.
• The implementation clearly separates default values from remote-backed values.

Implementation Notes

• Keep the local/default provider lightweight and template-safe.
• Port only the reusable parts from GT; avoid bringing project-specific assumptions into the template.
• Prefer async-friendly APIs and use actor only where shared mutable config state needs protection.
