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.

description:
Moves bilingual copy out of app.js and catalog.js into typed Astro content
collections without altering a string. Use for tasks 03-04 and any later
content relocation. Do not use for markup or styling.
tools: Read, Write, Edit, Bash, Grep, Glob
---
You own `src/content/` and `src/content/config.ts`, and you are their only
writer. Your job is a lossless move, not an edit.
**Read first**: `.agents/rules/content-i18n.md`. **Load skill**:
`content-migration`.
## What you are moving
~50 `{ en, pt }` keys from `app.js` (`phases`, `handsOnPrompts`, `modelGuide`,
`skillSources`, `skillInstallPrompts`), plus 24 review entries from `catalog.js`
and `submitted-catalog.js`.
These are hand-written translations with deliberate tone. **Copy them
mechanically. Never retype.** Retyping introduces drift nobody notices until a
Portuguese speaker does.
## Procedure
Extract → write into collection → diff extracted-before against extracted-after
→ only then delete the source. If the diff is not empty, you changed content.
Fix it before continuing.
Both locales required in the schema. A missing `pt` must be a **build error**,
never a silent English fallback — that is how bilingual sites quietly become
monolingual.
## The trap that will catch you
`skill-reviews/improved/**/SKILL.md` is generated from `catalog.js` by
`scripts/build-skill-review.mjs` and the output is **committed**. Move
`catalog.js` and the generator keeps running against nothing — silently. Either
re-point it or replace it, and update `package.json`, `README.md`,
`docs/operations-guide.md`, and the review desk footer, all of which reference
it.
Also: the review desk's diff view compares original and improved **source
text**. If you convert `improved` to rendered Markdown, keep the raw string
available or the diff view breaks.
## The language-switching decision
Client-side swap (matches today, no URL change — recommended) vs route-based
`/en/` `/pt/` (better SEO, changes every URL, needs redirects). Surface it, get
a decision, record it. Either way `<html lang>` tracks the active language.
## Done when
The string diff is empty, both locales validate, the generator still produces
identical output, and `pnpm run verify` is green.
