[repo-assist] Bump Fantomas to 7.0.6 and fix stale NuGet/login comment

[github-actions]

🤖 This PR was created by Repo Assist, an automated AI assistant.

Changes

1. Fantomas 7.0.1 → 7.0.6 (.config/dotnet-tools.json): a safe patch-version bump of the code-formatting tool used by CheckFormat/Format build targets. Verified CheckFormat reports "No files need formatting" with the new version, so no source reformatting was required.
2. Stale comment fix (.github/workflows/push-master.yml): a previous Dependabot PR bumped the pinned SHA for NuGet/login from v1.1.0 to v1.2.0, but left the adjacent # this hash is v1.1.0 comment unchanged. Updated the comment to correctly say v1.2.0 to avoid confusing future maintainers/dependabot reviewers.

Rationale

Both are low-risk engineering hygiene fixes: keeping tooling current and keeping in-repo documentation/comments accurate and in sync with actual pinned versions.

Trade-offs

None identified — Fantomas 7.0.6 is a patch release within the same major/minor line already in use, and the comment fix is purely documentation.

Test Status

• dotnet tool restore: ✅ succeeded, Fantomas 7.0.6 installed
• dotnet run --project build/build.fsproj -t CheckFormat: ✅ passed ("No files need formatting")
• dotnet run --project build/build.fsproj -t Build: ✅ succeeded, 0 errors (pre-existing warnings only, unrelated to this change)
• Full RunTests was not executed for this docs/tooling-only change since it does not affect runtime or test code; Build + CheckFormat cover the affected surface.
