Subject: [PATCH] CI: add SonarQube analysis workflow + Codecov badge

Add Sonar.yml running dotnet-sonarscanner on develop pushes (and
workflow_dispatch). Community-Edition Sonar has no branch/PR support,
so analysis is scoped to the long-lived develop branch; PR build/test
feedback stays in CI.yml.

Build/test run in Release with an explicit restore to mirror CI.yml,
coverage is collected via coverlet (opencover) and uploaded to Codecov.
Add the Codecov badge to the README.
