fix(skills): use stable logical node_modules path for skills symlink (#718)

Before: symlink target resolved to pnpm's content-addressable path like
`../../node_modules/.pnpm/vite-plus@0.1.1_.../node_modules/vite-plus/skills/vite-plus`

After: symlink target uses the stable logical path
`../../node_modules/vite-plus/skills/vite-plus`

Falls back to the resolved path when the logical path doesn't exist or
points to a different location.
