Marcos Paulo 48c31dc1b3 build: migrate from npm to pnpm
Ten git worktrees each carried their own 225 MB node_modules (1.1 GB across
five) and paid 11s per `npm ci`. pnpm hardlinks from a shared store: the same
five worktrees cost ~250 MB total, and a fresh install is 4s.

What changed beyond the mechanical rename:

- `overrides` moved to `pnpm-workspace.yaml`. pnpm 11 does not read the `pnpm`
  field in package.json *or* npm's top-level `overrides`, and it fails silently
  — the vite/defu/language-server pins would have quietly stopped applying.
- Build scripts are blocked by default in pnpm; esbuild and sharp are allowed
  explicitly via `allowBuilds` (renamed from `onlyBuiltDependencies` in 11).
- `packageManager` + `engines` pin the toolchain.
- gate.sh rejects a package-lock.json/yarn.lock/bun.lock outright, so an agent
  running `npm install` out of habit fails loudly instead of building a second,
  divergent dependency tree.
- CI bootstraps pnpm with `npm install --global pnpm@11.25.0` rather than
  corepack (unbundled as of Node 25) or pnpm/action-setup (this self-hosted
  act-runner has never run a job; fetching a third-party action is not
  something to discover on the first one).

Two pre-existing CI bugs fixed while in the file:

- the gate installed with `npm install --package-lock=false`, which discarded
  the lockfile the previous session had just fixed.
- the visual-regression step imported `playwright`, which is not a dependency,
  and `visual-regression.mjs` has no compare mode anyway — in CI it overwrote
  its own baselines and passed unconditionally. Removed with a comment; it
  comes back when it can diff.

The `publish` job is now manual (`workflow_dispatch`). During the migration
dist/ holds three HTML files against the live pages branch's ten, so publishing
on every push to main would take the site down to a stub. Restore at task 20.

HANDOVER.md's incident log still says npm where it describes what happened at
the time; that is history, not a missed rename.

# Checklist: before you call a page migrated
- [ ] URL identical to the old one, **trailing slash included**
- [ ] Any query params the old page honoured still work (`?author=`, `?skill=`,
`?view=`, `?file=`, `?compare=`, `?render=`)
- [ ] Rendered text content diffs clean against the pre-migration snapshot — or
every difference is listed and justified
- [ ] Same number of JS bytes or fewer; a previously-zero-JS page still ships
zero
- [ ] `<title>`, `<meta name="description">`, and `<meta name="viewport">`
preserved
- [ ] One `<h1>`; heading levels do not skip
- [ ] Every ARIA attribute from the original survived (`verify.mjs` asserts
several)
- [ ] No external `<script>`, `<link>`, `@import`, or `url()`
`node scripts/audit-ui.mjs` green
- [ ] Internal links go through `BASE_URL`, not hand-written absolute paths
- [ ] Screenshots at 560 / 800 / 1100 / 1600 px compared against the old page
- [ ] `<html lang>` correct and still switching with the language toggle
- [ ] `pnpm run verify` green with no assertion deleted
