1.0.8

- Expanded diplomacy with clearer relationship information, better proposal feedback, gold gifts, shared-war context, and visible reasons behind diplomatic reactions.

- Improved AI turn planning so computer players defend cities and important units more reliably, avoid wasting idle military actions, and make steadier strategic choices.

- Made game popups less disruptive so outcome screens, guidance, and modal messages no longer dim or hide the map unnecessarily.

- Improved city and production requirement labels across supported languages, including clearer missing-resource messages.

- Strengthened map validation to catch broken or incomplete map data before it can cause confusing in-game behavior.

- Added Linux release support for Steam and itch.io.
