ci: collect and upload coverage to Codecov; docs: add badge

- test: add coverlet.collector to JSSoft.Randora.Tests for XPlat Code Coverage
- ci(build-and-test): collect coverage during dotnet test and upload via codecov-action
- docs(README): add Codecov badge; add tuple/value tuple and nullable usage
- ci(pack): keep push-only secrets usage; PR packaging split into separate workflow (no secrets)
