--noRestore flag does not skip MSBuildCracker restores #4527

Description

The --noRestore CLI flag is parsed and stored in CrackerOptions.NoRestore, but MSBuildCrackerResolver.mkOptionsFromDesignTimeBuildAux hardcodes /restore in the dotnet msbuild arguments, so the flag has no effect on the MSBuildCracker code path.

This causes sequential per-project restores during the project cracking phase, adding ~20s to compilations for projects with many transitive references (~25 in our case), even when the user passes --noRestore.

Repro code

No F# repro needed — this is a CLI/infrastructure issue. Steps:

1. Have a project with many transitive ProjectReferences
2. dotnet restore the root project
3. dotnet fable --noRestore
4. Observe that Fable still runs dotnet msbuild ... /restore for each referenced project during the "Parsing" phase

The /restore is hardcoded at MSBuildCrackerResolver.fs line 146:

let arguments =
    $"/restore /t:%s{targets} %s{properties} --getItem:FscCommandLineArgs ..."

options.NoRestore is available on CrackerOptions but never checked.

Expected and actual results

Expected: With --noRestore, the MSBuild design-time build should omit /restore, skipping per-project restores.

Actual: /restore is always included regardless of the flag.
