Scope jiti filesystem transform caches for OpenClaw plugin loaders by package version and package.json install metadata so stale transforms cannot survive upgrades or package reinstalls.
Covers the central plugin module loader and the plugin SDK root alias CJS loader, while preserving jiti filesystem-cache env opt-outs and the TMPDIR cwd guard.
