fix: make E2E tests discoverable by Playwright

Refactored e2e/tests.ts to e2e/tests.spec.ts with:
- Synchronous file discovery using Node fs APIs
- Direct test registration inline (no imports of problematic modules)
- Simplified step interpreter for basic test actions
- Proper test.describe/test registration for Playwright

Tests are now discovered and executed. Some complex steps
not yet implemented, but core infrastructure works.
