Retain the unsuperseded macOS RAM-detection contribution from PR #13 while making every optional probe fail closed. The shared MPS device, loader, cache, and dtype work is already present on current main and is intentionally not duplicated.
Salvage the still-relevant functional work from PR #48: add non-UTF-8 console fallbacks, use platform temporary directories, make pipeline log output encoding-safe, and defer heavyweight analysis imports. The obsolete contributed CI workflow and already-corrected remote URL are intentionally excluded.
