feat: add privacy-preserving telemetry and error aggregation

- Update smoke-test.mjs to output structured summary with logs
- Update telemetry-aggregator.mjs to collect from unit, smoke, and load tests
- Update run-unit-tests.mjs to log output to artifacts/test_unit.log
- Ensure PII sanitization in telemetry reports
