True native foundations and upstream frameworks

Master: https://github.com/stacksjs/the-settlers-iii-remake/issues/4

Craft owns graphics, native hosting, and platform capabilities. stx owns compilation/reactivity. ts-css owns style semantics. Stacks owns build and release orchestration. The game consumes published contracts.

Completion gate

All mandatory child acceptance criteria require verified implementation evidence. Research, compilation, prototype victory, and uploaded but unprocessed binaries are not equivalent to completion. HomeOS integration is independent of supported game platform delivery.
