refactor: remove Playwright screenshots, improve runner compatibility

- Remove Step 6 (dev server + screenshots) - too complex for GH Actions sandbox
- Add fallback for missing template-sync-state.json (use initial baseline SHA)
- Add better-sqlite3 rebuild instructions for --ignore-scripts fallback
- Recompile lock.yml without screenshot artifact upload step

 # GitHub Copilot Instructions
 
+## Project Overview
+
+This is **TechWatching.dev**, Alexandre Nédélec's personal blog at https://techwatching.dev. It is a statically generated site built with:
+
+- **Nuxt 4** — Vue.js meta-framework (compatibility date `2024-07-11`)
+- **Nuxt UI v3** (`@nuxt/ui`) — UI component library based on TailwindCSS v4
+- **Nuxt Content v3** (`@nuxt/content`) — Markdown/YAML content management with SQLite
+- **TailwindCSS v4** — Utility-first CSS
+- **@nuxtjs/seo** — SEO, OG images, schema.org, sitemap
+- **TypeScript** — strict typing throughout
+
+## Development Environment
+
+### Package Manager
+
+This project uses **pnpm** (version specified in `package.json` → `"packageManager": "pnpm@10.29.2"`). Always use `pnpm` — never `npm` or `yarn`.
+
+The `.npmrc` sets `shamefully-hoist=true`.
+
+### Bootstrap
+
+```bash
+pnpm install           # install all dependencies
+```
+
+### Common Commands
+
+| Command | Description |
+|---------|-------------|
+| `pnpm dev` | Start dev server at http://localhost:3000 |
+| `pnpm build` | Build for production (SSR) |
+| `pnpm generate` | Generate static site (prerendered) |
+| `pnpm preview` | Preview production build |
+| `pnpm lint` | Run ESLint |
+| `pnpm lint:fix` | Run ESLint with auto-fix |
+| `pnpm typecheck` | Run TypeScript type checking via `nuxt typecheck` |
+
+### CI Validation
+
+The CI workflow (`.github/workflows/ci.yml`) runs on every push:
+
+1. `pnpm install` — install dependencies
+2. `pnpm run lint` — **must pass with zero errors**
+3. `pnpm run typecheck` — **must pass with zero errors**
+
+Always run both `pnpm lint` and `pnpm typecheck` before committing. Fix all lint and type errors before marking work as done.

+
+### Key architecture notes
+
+- **Static generation**: all routes prerendered via `routeRules: { '/**': { prerender: true } }` and Nitro crawl
+- **Content collections**: defined in `content.config.ts` using `defineCollection` + zod schemas; collection names are `index`, `posts`, `speaking`, `goodies`, `goodiesPage`, `content`
+- **Server handlers**: must import from `@nuxt/content/server` and pass `event` as first arg: `queryCollection(event, 'posts')`
+- **Commit messages**: follow Conventional Commits (see `.github/git-commit-instructions.md`)
