Sandbox Npm Install

If you're running npm installs inside a Docker sandbox with virtiofs mounts, you've probably hit those fun SIGILL crashes from native binaries like esbuild or rollup. This skill bundles a script that installs packages on the container's local ext4 filesystem and symlinks node_modules back into your workspace, sidestepping the mmap alignment issues that plague aarch64. You'll need to rerun it whenever package.json changes, and the symlink will look broken on your host, but that's fine since node_modules is gitignored anyway. It's a specific fix for a specific problem, and if you've been debugging segfaults in your build tools, you already know whether you need this.
