Merge main into FEAT-ExpressionFactoryExtensionPoint branch

[Copilot]

Merges 470 commits from main into the FEAT-ExpressionFactoryExtensionPoint branch, reconciling divergent histories.

Key Conflict Resolutions

Core API changes (FEAT branch preserved):

• ExpressionExtensions.Build() - new public API combining decompilation, factory expansion, and optimization
• Decompile(), Optimize(), Evaluate() - changed to internal visibility
• DecompiledQueryProvider and DecompiledQueryable - migrated to use Build() API
• EntityFramework async providers - updated to use Build() API

Main branch updates integrated:

• Processor.cs - added ldobj and prefix opcode support from Add support for ldobj opcode hazzik/DelegateDecompiler#309, Fix support for prefix opcodes hazzik/DelegateDecompiler#304
• Test infrastructure - EF Core 10 test projects added
• Build configurations and workflows - accepted latest from main

Configuration files: Accepted main versions for solution files, workflows, and build properties to ensure compatibility with latest CI/CD infrastructure.

What This Enables

The FEAT branch introduces expression factory expansion as a new pipeline stage, allowing custom expression transformations to be registered via [ExpressionFactory] attribute. The merge ensures this functionality benefits from all recent main branch improvements including new opcode support and updated dependencies.

// Before (main): Direct decompilation
var result = expression.Decompile().Optimize();

// After (FEAT): Factory expansion included
var result = expression.Build();  // Decompile → ExpandFactories → Optimize

Warning

Firewall rules blocked me from connecting to one or more addresses (expand for details)

I tried to connect to the following addresses, but was blocked by firewall rules:

• http://crl3.digicert.com:443/DigiCertTrustedG4TimeStampingRSA4096SHA2562025CA1.crl
  • Triggering command: dotnet build -c Debug -p:DisableGitVersionTask=true (http block)

If you need me to access, download, or install something from one of these locations, you can either:

• Configure Actions setup steps to set up my environment, which run before the firewall is enabled
• Add the appropriate URLs or hosts to the custom allowlist in this repository's Copilot coding agent settings (admins only)
