Development improvement unlock-path fix
2026-03-09
- Fixed `/nations/[id]/development` improvement options so military and defense facilities (including **Army Base**) are now visible in the selector instead of being hidden behind economy-only option filtering.
- Improvement detail payloads for newly surfaced options now include deterministic era/tech/cost/build metadata from canonical config, so requirement panels stay populated instead of showing missing detail states.
