[victor-teles]

Closes #2

---

Summary by cubic

Raise minimum PHP to 8.2 and bump thecodingmachine/safe to v3. CI now tests PHP 8.2–8.4, uses Node 24 via actions/setup-node@v6, disables fail-fast, and simplifies Composer/npm installs with caching and Playwright setup for faster, stable runs.

• Dependencies
  • Dev: upgrade phpstan/phpstan to ^2.0 and thecodingmachine/phpstan-safe-rule to ^1.4
  • Update @zoon/rialto to 1.6.6
  • Refresh composer.lock
