/**
* v1.4.43 QoL (L3) — write the active package.json version into
* `public/sw-version.js`. The Service Worker (`public/sw.js`) loads
* this file via `importScripts('/sw-version.js')` and reads
* `self.__APP_VERSION__` to key its `CACHE_VERSION`.
*
* Pre-fix the SW carried a hand-bumped literal that drifted four
* releases stale; the `activate`-step's old-cache eviction became
* a no-op for every deploy in v1.4.38.4 → v1.4.42. Running this
* script as a `prebuild` step re-anchors the version on every build,
* so the eviction now fires reliably.
*
* Idempotent: writes the file unconditionally. Safe to commit the
* generated file or `.gitignore` it — either way `pnpm build` reruns
* the generator.
