feat: integrate TimeWarp.Nuru.DevCli shared endpoints

Replace custom clean, check-version, and self-install endpoint
implementations with shared endpoints from TimeWarp.Nuru.DevCli.

- Delete local endpoints/clean.cs, check-version.cs, self-install.cs
- Register services required by shared endpoints in dev.cs
  (IRepoCleanService, NuGetVersionService, GitTagCheckService,
  IRepoConfigService) and add .DiscoverEndpoints()
- Add DevCli and static TimeWarp.Nuru.Unit global usings so the
  shared content files resolve correctly
- Suppress CA5399/IL2104/IL3053/IDE0065 from package content

Closes kanban task 021.
