Document ILRepack incompatibility with .NET 6+ AOT compilation

[Copilot]

ILRepack is documented in STRONG_NAME_RUNTIME_ERROR.md as a solution for strong-name signing issues, but post-build IL manipulation breaks .NET 6+ AOT compilation (PublishAot). Verified that ILRepack is not currently implemented—only documented as an option.

Changes

New Documentation

• AOT_COMPATIBILITY.md: Technical details on why ILRepack fails with AOT, alternatives (source embedding, separate assemblies), and testing guidance
• AOT_CHECKLIST.md: Pre-submission verification showing ILRepack not implemented, current targets (netstandard2.0, net48) don't support AOT

Updated Documentation

• STRONG_NAME_RUNTIME_ERROR.md: Added AOT compatibility warnings to ILRepack section, updated comparison matrix with AOT column
• STRONG_NAME_DECISION.md: Cross-referenced AOT compatibility guide in ILRepack alternative
• README.md: Added links to AOT compatibility documentation

Compatibility Matrix

Approach	.NET Framework	.NET 6+ (no AOT)	.NET 6+ (with AOT)
ILRepack	✅ Safe	✅ Safe	❌ Incompatible
CS8002 Suppression (current)	✅ Safe	✅ Safe	✅ Safe

Repository is currently AOT-compatible. Documentation prevents future AOT issues if ILRepack is implemented.
