SP1.1: Complete :dispatcher-agent Gradle module integration with CI/CD and SonarQube configuration

[Copilot]

The :dispatcher-agent Gradle submodule was scaffolded but lacked per-submodule settings required for test execution, code quality checks, and coverage analysis in CI/CD pipelines. This PR adds missing configuration to fully integrate the module into the build system while maintaining architectural constraints.

Changes

Root Build Configuration (build.gradle.kts)

• Add :dispatcher-agent:test and :dispatcher-agent:integrationTest to root-level task delegations
• Update SonarQube sonar.sources, sonar.tests, and sonar.java.binaries properties to include dispatcher-agent
• Add dispatcher-agent paths to sonar.junit.reportPaths and sonar.coverage.jacoco.xmlReportPaths
• Include dispatcher-agent in aggregated jacocoAggregatedReport (execution data, sources, classes)

Dispatcher-Agent Module (dispatcher-agent/build.gradle.kts)

• Configure jacocoTestReport task to generate XML reports at dispatcher-agent/build/reports/jacoco/test/jacocoTestReport.xml

CI/CD Workflows

• gradle-java21.yml: Add :dispatcher-agent:ktlintCheck to code formatting step; include dispatcher-agent artifacts in sonar inputs upload
• sonarqube.yml: Add dispatcher-agent test exclusions to prevent re-running tests during SonarCloud analysis

Verification

✓ Architectural constraints preserved:

• :dispatcher-agent depends on :core only (not :desktop-ui)
• :core and :fast-sim remain free of Koog/Ollama LLM framework dependencies

✓ All tests pass: 2,194+ core tests + 35+ dispatcher-agent tests

✓ Coverage reporting active: JaCoCo XML reports generated and aggregated; SonarQube configuration complete
