Use GlobalAnalyzerConfigFiles with global_level=-1 for analyzer configuration

[Copilot]

Users cannot override analyzer rules in their .editorconfig when MeziantouAnalysisMode is set to None or Default because the package's configuration files take precedence.

Changes

• MSBuild props: Changed EditorConfigFiles to GlobalAnalyzerConfigFiles in build/Meziantou.Analyzer.props
• Configuration precedence: Set global_level = -1 (was 0) in generated .editorconfig files to ensure user configs override package defaults
• Generator: Updated DocumentationGenerator/Program.cs to emit the new global level

This follows Microsoft's guidance for Global Analyzer Config files and ensures users can selectively enable/disable rules after setting a baseline via MeziantouAnalysisMode.

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:

• www.nuget.org
  • Triggering command: /usr/share/dotnet/dotnet /usr/share/dotnet/dotnet exec --runtimeconfig /home/REDACTED/work/Meziantou.Analyzer/Meziantou.Analyzer/tests/Meziantou.Analyzer.Test/bin/Debug/net10.0/Meziantou.Analyzer.Test.runtimeconfig.json --depsfile /home/REDACTED/work/Meziantou.Analyzer/Meziantou.Analyzer/tests/Meziantou.Analyzer.Test/bin/Debug/net10.0/Meziantou.Analyzer.Test.deps.json /home/REDACTED/work/Meziantou.Analyzer/Meziantou.Analyzer/tests/Meziantou.Analyzer.Test/bin/Debug/net10.0/testhost.dll --port 32843 --endpoint 127.0.0.1:032843 --role client --parentprocessid 4447 --datacollectionport 35531 --telemetryoptedin false (dns 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)

<issue_description>Is your feature request related to a problem? Please describe.
I am not able to disable all rules using the MeziantouAnalysisMode set to None and then define what rules I want to apply solution-wide in my .editorconfig file in the root folder of the solution.

Describe the solution you'd like
Based on the documentation here: https://learn.microsoft.com/en-us/dotnet/fundamentals/code-analysis/configuration-files#naming

Use GlobalAnalyzerConfigFiles item to include the rule files instead of EditorConfigFiles item: https://github.com/meziantou/Meziantou.Analyzer/blob/36df944d2c8e00e9786ce888c645583ca0192f0f/src/Meziantou.Analyzer.Pack/build/Meziantou.Analyzer.props</issue_description>

<agent_instructions>Can you update the MSBuild property name? Also, can you set the global editor config level to -1 in the generator?</agent_instructions>
