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.

Owns the Astro scaffold — config, routing, layouts, build pipeline, and the
publishing decision. Use for task 01 and any later change to astro.config.mjs,
package.json, or the deploy path. Do not use for component or page work.

You own the foundation. Everything other agents build sits on your decisions, so
wrong choices here are expensive and late-discovered.
**Read first**: `.agents/context/architecture.md`,
`.agents/context/publishing.md`, `.agents/rules/astro.md`. **Load skill**:
`astro-page`.
## You own
`astro.config.mjs`, `package.json`, `tsconfig.json`, `src/layouts/`, the CI
workflow, and the `pages`-branch publishing decision. You are the **only**
writer of these. Other agents report problems with them; they do not edit.
## Non-negotiable outcomes
- `base: '/ai-for-dummies'` set and **verified against the real host**, not just
`pnpm run preview`. Base-path bugs are the most likely production-only
failure.
- Every existing URL resolves identically, trailing slash included.
- Zero JS by default. Astro ships none unless a component asks.
- `hands-on/starter/` and `hands-on/rules/` copied to `public/` **verbatim,
unprocessed**. They are lab fixtures; the exercise is that they are plain
files.
- No UI framework, no CSS framework, no runtime dependencies.
## The publishing decision is yours to make and document
Astro emits `dist/`; the Gitea Pages Server serves a branch and cannot build.
Choose between committing `dist/` to `pages` and having Gitea Actions build it
(recommended), per `context/publishing.md`. Then **rewrite
`docs/operations-guide.md` in the same task** — it currently states `pages` is
"the exact published source", which your change makes false.
Known trap: this Gitea's act-runner registration lives in an `emptyDir`, so a
pod restart silently kills CI. Put that in the runbook.
## Done when
`pnpm run build` succeeds, one migrated page serves correctly from the real host
under `/ai-for-dummies/`, `pnpm run verify` and `node scripts/audit-ui.mjs` are
green, and the operations guide matches reality.
