ci: generate lcov coverage report for SonarCloud

[guyinwonder168]

Summary

• Add vitest.config.ts with @vitest/coverage-v8 reporter set to text + lcov so coverage/lcov.info is generated
• Update CI workflow to run npx vitest run --coverage before SonarCloud scan
• Point sonar.javascript.lcov.reportPaths to coverage/lcov.info in sonar-project.properties

Without this, SonarCloud shows 0% coverage because v8 defaults to clover/json/html only.

Verification

• npx vitest run --coverage locally produces coverage/lcov.info with 99.11% line coverage
• CI job updated to generate coverage before SonarCloud upload

Review Notes

The PR correctly configures SonarCloud coverage reporting:

1. .github/workflows/ci.yml - The sonarqube job now depends on test job, sets up Node.js 22, installs dependencies, and runs coverage before scanning.

2. sonar-project.properties - Correctly points to coverage/lcov.info for the LCOV report path.

3. vitest.config.ts - Configures coverage reporters (text, lcov) which will work with the already-installed @vitest/coverage-v8 package.

The implementation follows standard practices for Vitest + SonarCloud integration.
