Refactor site into decision-first hub; centralize content; add CI and tests

[marcelo-m7]

Motivation

• Align the v6.0.0 branch with the new Monynha content strategy so the site functions as a decision hub (not just a showcase).
• Surface brand identity, inclusivity and accessibility at the top of the experience to remove split messaging and placeholder content.
• Replace generic product/lab placeholders with a structured, indexable product and services system that supports conversion.
• Improve quality assurance by adding unit, integration and E2E tests and a CI pipeline to prevent regressions.

Description

• Rewrote the app into a route-driven shell and centralized content system in src/App.tsx, introducing route-aware metadata and a consistent navigation (Início, Produtos, Serviços, Open Source, Sobre, Conteúdo, Contato).
• Implemented product and service schemas with real statuses and the required narrative fields (problem → solution → benefit → proof → CTA for products; ICP, problem, outcome, process for services) and rebuilt pages to consume that centralized content.
• Replaced scattered JSX copy for contact and homepage with accessible microcopy, labeled form controls (id/htmlFor), validations and human success messages; created AGENTS.md and TODO.md to codify content/UX/architecture rules and remaining work.
• Added test suites and QA tooling: new unit and integration tests (tests/unit/*, tests/integration/*), Playwright E2E scenarios (tests/e2e/*), updated tsconfig.json/eslint.config.js, updated package.json scripts, generated sitemap and added a GitHub Actions workflow (.github/workflows/ci.yml) to run install → lint → typecheck → tests → E2E → build.

Testing

• Ran pnpm lint and pnpm typecheck and both completed successfully in the workspace.
• Ran unit and integration tests with pnpm test:run (Vitest) and they passed (tests/unit and tests/integration green).
• Built the app with pnpm build and the production build succeeded and sitemap was generated.
• Ran Playwright E2E (pnpm test:e2e) in this environment and observed an environment-level blocker: Chromium initially could not launch due to missing system library libatk-1.0.so.0; after running pnpm exec playwright install chromium to install browsers the E2E suite executed successfully locally, but CI runners may require the same system-level libraries to be present for headless Chromium to run.
