Download Unity CLI 1.0.0.20006

Highlights of 1.0.0-beta.6 (full notes at the release notes URL):
- unity projects create and unity projects link vcs can now create the repository through gh, glab, or tea for hosts with no REST client: GitHub Enterprise Server, self-managed GitLab, self-hosted Gitea/Forgejo.
- unity projects clone and unity projects link vcs accept a plain git URL now, including full SSH transport, so any git host works.
- unity projects verify is a new command that checks a project for broken .meta files, duplicate GUIDs, and unresolved merge conflicts without needing an Editor or a license.
- unity build now writes a redacted build provenance manifest next to its output and prints a periodic stall heartbeat, with a new --timeout flag.
- unity collaboration (unity collab) is part of every build now instead of development builds only.
- unity test gains --shard, --retries, and --rerun-failed for CI, and now uses exit code 8 specifically for failing tests, reserving 6 for a run that never reached a verdict.
