feature: add apple silicon native macOS support (#81)

* feature: add apple silicon native macOS support - #81 * (macos): Fix crash This fixes a crash when viewing the rear camera * fix(macos): keep interpolated presentation on main thread * fix(macos): supply Retro-WFC payload during setup * perf(windows): compile out flat-memory fallback check * remove duplicate smoke test * test(macos): name and focus host platform tests * fix(macos): validate Retro-WFC payload cache * fix(payload): preserve staged file access failures * Limit flat-page checks to variable-page hosts --------- Co-authored-by: patchzyy <64382339+patchzyy@users.noreply.github.com>
