Subject: [PATCH] Multi-target Microsoft.EntityFrameworkCore.Tools for net8.0,
 net9.0, net10.0
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Add per-TFM dependency groups in the nuspec so that the appropriate
version of Microsoft.EntityFrameworkCore.Design is resolved based on
the consumer's target framework:
- net8.0 → Design >= 8.0.0
- net9.0 → Design >= 9.0.0
- net10.0 → Design >= 10.0.0

This prevents MissingMethodException when the Tools package pulls in a
Design version incompatible with the user's other EF Core packages.

Fixes #38107
