feat(health): pack ZB.MOM.WW.Health 0.1.0 + README + register health component in indexes

- Added PackageTags to all 3 library csproj files (health-checks;aspnetcore/akka/efcore;scada;wonderware;zb-mom-ww)
- Full solution dotnet test: 58 tests green (32 Akka + 20 core + 6 EFCore)
- dotnet pack -c Release produces ZB.MOM.WW.Health.0.1.0.nupkg, ZB.MOM.WW.Health.Akka.0.1.0.nupkg, ZB.MOM.WW.Health.EntityFrameworkCore.0.1.0.nupkg; artifacts/ not committed
- ZB.MOM.WW.Health/README.md: overview, packages table, consumer matrix, versioning, build/test/pack instructions, status note
- components/README.md: Health row added to component registry
- CLAUDE.md: Health row in Component-normalization table + Health paragraph; intro updated from "two pieces" to "three pieces"
- upcoming.md: Health checks item checked off with pointer to components/health/ and ZB.MOM.WW.Health/
- components/health/README.md: status updated from "Draft / scaffolded / follow-on" to "Built @ 0.1.0"
