Harden analyzer precision and code-fix safety

[georgepwall1991]

Summary

• reduce analyzer noise by tightening DI003, DI011, and DI014 behavior to high-confidence cases
• improve DI007 precision and align docs/sample output with current analyzer behavior
• harden DI005, DI006, DI008, DI003, and DI009 code-fix behavior so unsafe or brittle actions are not offered

Verification

• dotnet test DependencyInjection.Lifetime.Analyzers.sln
