CI: Add SonarCloud integration for abbenay

[Hrithik-Gavankar]

Summary

• Add sonar-project.properties for SonarCloud analysis of the TypeScript monorepo (packages/daemon, packages/vscode).
• Update CI to generate daemon coverage (lcov.info), upload it as a SonarCloud artifact, and store PR metadata for branch analysis.
• Add a finalize workflow that runs after CI and uploads results to SonarCloud (same pattern as other Ansible DevTools repos, e.g. vscode-ansible).

SonarCloud project details

• Organization: redhat-developer
• Project key: redhat-developer_abbenay
• Coverage: packages/daemon/coverage/lcov.info
• CI secret required: CICD_ORG_SONAR_TOKEN_CICD_BOT

Blockers / follow-up

SonarCloud access for the redhat-developer org is required before this can fully work. A separate ticket has been raised to:

• Create/import the redhat-developer/abbenay project in SonarCloud
• Grant DevTools team access
• Configure the CI token in GitHub Actions secrets

Until that is done, the finalize workflow is expected to fail.

Test plan

• CI passes (lint-and-test, build, package-python)
• Daemon coverage artifact (sonar-coverage) is uploaded
• After SonarCloud access is granted, finalize workflow completes successfully
• SonarCloud shows analysis results on the PR
