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 — verify the SW build step + the SW source contract.
*
* Pre-fix `public/sw.js` hard-coded `const CACHE_VERSION = "v1.4.38.4"`
* which drifted four releases stale. The current shape:
* - `scripts/generate-sw-version.mjs` writes `self.__APP_VERSION__`
* into `public/sw-version.js` from `package.json`.
* - `public/sw.js` `importScripts('/sw-version.js')` and reads
* `self.__APP_VERSION__` (falling back to a literal).
