+/**
+ * Windows variant of `resolve()`. Mirrors Node's `path.win32.resolve`
+ * semantics enough for the WASI shim's needs (drive-letter absolutes
+ * + UNC paths + per-drive cwd lookups via `process.env`/`process.cwd`).
+ *
+ * Why this is needed: on Windows, `FileDescriptor.realPath` is the
+ * host realpath returned by `fs.realpathSync(realPath, 'utf8')` — the
+ * backslash form `D:\…`. The POSIX-only `resolveImpl` below only
+ * treats `/` as a separator, reads `D` as non-`/`, decides realPath
+ * is "relative", and produces a garbage joined path. Downstream
+ * `fs.openSync(garbage)` then returns `EINVAL` and the WASI caller
+ * sees a permanent failure. This function gives us the correct
+ * Windows-style resolution without taking a Node-only `path` import
+ * (which would break browser bundles of this package).
+ *
+ * Cribbed from Node's `lib/path.js` `win32.resolve()` (MIT-licensed),
+ * trimmed to what WASI realpath resolution actually exercises.
