fix: use AfterTargets="Restore" to support NuGet credential helpers for private feeds

[Copilot]

Description

Users relying on NuGet Credential Helpers for private feeds had dotnet tool restore fail because auth (performed during MSBuild's Restore target) hadn't happened yet when the Husky target ran under BeforeTargets="Restore".

• AttachCommand.cs — generated MSBuild target now uses AfterTargets="Restore" instead of BeforeTargets="Restore;CollectPackageReferences"
• docs/guide/automate.md — updated both the primary and multi-framework XML snippets to match
• docs/guide/submodules.md — updated the submodule attach example snippet to match
• AttachCommandTests.cs — added assertions that the generated target has AfterTargets="Restore" set and no BeforeTargets

Before / After

<!-- Before -->
<Target Name="husky" BeforeTargets="Restore;CollectPackageReferences" Condition="'$(HUSKY)' != 0" ...>

<!-- After -->
<Target Name="husky" AfterTargets="Restore" Condition="'$(HUSKY)' != 0" ...>

Running after Restore ensures credential helpers have already performed the auth dance before dotnet tool restore is invoked. Husky hook installation has no dependency on running before package restore, so this is non-breaking.

This section details on the original issue you should resolve

<issue_title>Guide for automating installation can break for users that must authenticate to private NuGet feeds</issue_title>
<issue_description>### Details

The guide in automate has the user create a per-project Target that hooks BeforeTargets="Restore":

<Target Name="husky" BeforeTargets="Restore;CollectPackageReferences" Condition="'$(HUSKY)' != 0">
   <Exec Command="dotnet tool restore"  StandardOutputImportance="Low" StandardErrorImportance="High"/>
   <Exec Command="dotnet husky install" StandardOutputImportance="Low" StandardErrorImportance="High"
         WorkingDirectory="../../" />  <!--Update this to the relative path to your project root dir -->
</Target>

While this works for folks that use public NuGet feeds, or that have an active authentication to a private feed, it ill fail for users that are using NuGet Credential Helpers to access private feeds. This is because even with --interactive provided by default by the .NET CLI in .NET 10, the Restore Task is the thing that actually consumes that property to actually go and perform the authentication dances.

It would be less error-prone IMO to change this ordering to AfterTargets="Restore" if possible - that way you can ensure that any authentication required has been performed for you already.</issue_description>

<agent_instructions>I'm not sure if the suggestion by user is a good idea, I don't need this to be implemented unless the suggestion is actually a better choice over the existing behavior. we need to make sure also if we do this change, we're not causing any breaking changes otherwise this is not an option. give me your feedback about this issue</agent_instructions>

Pull request overview

Updates Husky’s generated MSBuild target hook point so NuGet authentication (including credential helpers for private feeds) completes during Restore before Husky runs dotnet tool restore / dotnet husky install.

Changes:

• Generate the Husky MSBuild target with AfterTargets="Restore" instead of BeforeTargets="Restore;CollectPackageReferences".
• Update the automation guide XML snippets to match the new target ordering.
• Extend AttachCommand unit tests to assert AfterTargets="Restore" and absence of BeforeTargets.

@copilot Does this have any conflicts with this commit? a51fed5

No conflicts. a51fed5 is the base commit this branch builds on top of. The only "inconsistency" it introduced was docs/guide/submodules.md containing the old BeforeTargets="Restore;CollectPackageReferences" syntax — which we didn't touch in the original PR commits and has since been updated in f28155a.
