feat(logging): add professional logging with pino and headless E2E tests - Add ILogger port interface in application layer - Implement PinoLogAdapter with Electron-compatible structured logging - Add NoOpLogAdapter for testing - Wire logging into DI container and all adapters - Create 32 E2E tests for automation workflow (headless-only) - Add vitest.e2e.config.ts for E2E test configuration - All tests enforce HEADLESS mode (no headed browser allowed)
