fix: Use type for type imports and literal types

Refactor `types.ts` to use `as const` for `GamePhase` and explicitly define the `GamePhase` type. This improves type safety and clarity. Additionally, update imports in other files to use `type` for type-only imports, further enhancing type safety and preventing potential runtime issues.
