Dependency audit: update ASP.NET Core component patches per TFM and reject incompatible Dependabot PRs

[Copilot]

Analysis of 5 open Dependabot PRs shows all safe updates already applied. Remaining PRs would break framework compatibility. This PR bumps ASP.NET Core component packages to the latest patch per target framework while leaving the private NuGet feed configuration unchanged.

Current State

All dependencies up to date:

• Microsoft.NET.Test.Sdk: 18.0.0
• Microsoft.AspNetCore.Components.WebAssembly: 8.0.21
• Microsoft.AspNetCore.Components.WebAssembly.DevServer: 8.0.21
• System.Net.Http.Json: 9.0.10
• System.Collections.Immutable: 9.0.10

Updates Applied

• OAT.Blazor.Components conditional package versions refreshed to latest patches:
  • net8.0 → Microsoft.AspNetCore.Components/Web 8.0.23
  • net9.0 → Microsoft.AspNetCore.Components/Web 9.0.12
  • net10.0 → Microsoft.AspNetCore.Components/Web 10.0.2
• No changes to nuget.config are retained; it remains pointed at the private feed.

Dependabot PRs Analysis

Close as applied:

• Bump Microsoft.NET.Test.Sdk from 17.14.1 to 18.0.0 #380: Test SDK 18.0.0 ✓
• Bump Microsoft.AspNetCore.Components.WebAssembly from 8.0.19 to 8.0.21 #378: WebAssembly 8.0.21 ✓

Reject (breaks compatibility):

• Bump Microsoft.AspNetCore.Components.WebAssembly.DevServer from 8.0.19 to 9.0.10 #379: DevServer 8→9 breaks OAT.Blazor (targets net8.0)
• Bump Microsoft.AspNetCore.Components.WebAssembly and 5 others #367: Outdated, same compatibility issue
• Bump Microsoft.NET.ILLink.Tasks from 8.0.18 to 8.0.20 #375: Explicit ILLink.Tasks reference unnecessary (transitive)

Framework-Specific Versioning

OAT.Blazor.Components intentionally uses conditional references per TFM and should not be unified.

Test Results

66/66 passing on net8.0, net9.0, net10.0; build succeeds after the package updates.

Original prompt

Create a unified dependency update PR that covers all the dependabot issues currently open but be caareful when updating dependencies to not update any that are framework specific across versions that will break compatibility with targeting (i.e. when one is specified now with to target a specific framework for two different versions that is intentional). Aftre updating be sure to run all tests across the supported framework versions to validate everything still working.

@copilot can you check nuget explicitly for the latest versions of Microsoft.AspNetCore.Components for each framework? It looks to me like, for example, there is an 8.0.23, which should only be for .net8. Find the latest version for each framework and update each conditional version definition appropriately.

Removed the added markdown docs and reverted nuget.config back to the private feed; dependency bumps remain (commit 68188d5).
