* Fix type/method import for .NET Framework instrumentation

Add ImportToCoreLibrary helpers to redirect type and method references to mscorlib when instrumenting .NET Framework targets. This ensures compatibility when the coverlet assembly (built for .NET 8) references types through System.Runtime, which does not exist on .NET Framework. Replaces direct ImportReference calls with these helpers to prevent runtime errors and ensure correct cross-targeting behavior.

* Delete coverage.net9.0.cobertura.xml in build process

Add deletion of coverage.net9.0.cobertura.xml file.

* Add regression test: Tracker uses mscorlib on .NET Framework

Introduce a regression test to verify that the injected Tracker class in instrumented .NET Framework assemblies references mscorlib instead of System.Runtime. The test uses Mono.Cecil to inspect type references and is only run on Windows if the sample assembly is available. Also, update usages of Document to explicitly reference Coverlet.Core.Instrumentation.Document for clarity.

- Add nuget.config to .gitignore to prevent accidental commits.
- Document .NET Framework TypeInitializationException fix (#1818).
- Note improvements for .NET Framework instrumentation (#1825).
- Add migration link to MTP mode in integration documentation.

* Remove DevelopmentDependency from coverlet.MTP.csproj

The project no longer marks its package as a development-only dependency, allowing it to be included as a regular dependency in consuming projects.

* Document fix for coverlet.MTP CS0400 build error (#1827)

Updated Changelog.md to note resolution of CS0400 build failure in coverlet.MTP caused by developmentDependency=true.
