Subject: [PATCH] Pin .NET SDK to 10.0.204 via global.json
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Today's nightly build on main failed restoring Installer with NU1004:
'Microsoft.NET.ILLink.Tasks version has changed from [10.0.8, ) to
[10.0.7, )'. ILLink.Tasks is bundled with the SDK, so its version
tracks whatever SDK the runner image happens to ship. The lockfiles
were generated against SDK 10.0.204 (runtime 10.0.8); the runner now
ships SDK 10.0.107 (runtime 10.0.7), and `--locked-mode` refuses to
proceed against the mismatch.

global.json tells the SDK host (and actions/setup-dotnet) to use 10.0.204
or higher within the same major.minor — so CI installs the SDK that
matches the lockfile instead of inheriting whatever the runner image
came with. Local dev and CI now agree on the SDK version, and the only
way to bump it is to update global.json and regenerate lockfiles in the
same commit.

Verified locally: `dotnet --version` → 10.0.204, `dotnet restore
--locked-mode` succeeds.

Note: dev's nightly.yml is already on 10.0.x. main's still has the
.NET 8.0 leftover but that'll clear on the next dev → main release.
