Marc-André Bombeck fea1d1e0b5 chore: strip planning tags from comments and enable the rule
Output of `node scripts/strip-planning-tags.mjs --write`: 3,157 comment
lines in 1,308 files lose the work-item identifier at their head. Release
versions and issue references stay; nothing outside comment text
changes, which the script checks per file against a comment-free
printout. healthlog/no-planning-tags is enabled at error level with this
commit, so the tree it lands on is clean.

/**
* v1.4.43 — 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.
