v0.4.1-alpha

Fix source setup packs that failed Generate & Build without a Rust installation. The shared packager now builds and includes the host native analyzer, stages its runtime libraries, and runs a synthetic-ROM SDK smoke test from the staged source tree. It rejects a host/target platform mismatch and clears developer analyzer overrides during validation.

This follows v0.4.0-alpha's generation recipes, computed-return fix, and bounded coverage tooling. Game setup packs can now generate with their bundled Python and C/C++ tools; Rust is required on the packaging host, rather than the player's machine.

Validation: two integration regressions, Windows extracted setup generation with Cargo excluded from PATH, a complete rebuild with the bundled Clang/Python toolchain, Linux/Windows/macOS CI, and the extracted self-contained Windows CLI smoke test. Four-platform game setup artifacts are checked separately before their releases.
