Migrations use the design-time DbContext, not your runtime CommandTimeout. Set the timeout via UseSqlServer(o => o.CommandTimeout(...)), the connection string Command Timeout, or Database.SetCommandTimeout before Migrate().

Fix: The command 'dotnet' could not be found on CI

Your CI runner cannot resolve dotnet because the SDK is not installed for that step, or it is installed but not on PATH. Use actions/setup-dotnet, pin a global.json, and export DOTNET_ROOT and ~/.dotnet/tools.
