Code Quality: Customizing directories to scan

Body

I've turned on GitHub Code Quality (https://github.com/orgs/community/discussions/177488) for an internal repo. The code is in C#, which was automatically detected. However, there are lots of warnings logged from *.g.cs files (generated code), which are not directly actionable (except by fixing the code generator, which is a different project).

.gitattributes has this:

*.g.cs linguist-generated=true

The files themselves have this:

	[System.CodeDom.Compiler.GeneratedCode("tool-name", "")]
	public sealed class GeneratedClassName
	{

This attribute documentation says it "can be used by code analysis tools to identify computer-generated code".

I would like the presence of metadata indicating tool-generated code to cause warnings in the code to be suppressed (or an option to ignore them).

Failing that, because the file name is *.g.cs, another solution would be to allow customizing the paths to scan in, as is possible for Code Scanning: https://docs.github.com/en/code-security/how-tos/scan-code-for-vulnerabilities/configure-code-scanning/customizing-your-advanced-setup-for-code-scanning#specifying-directories-to-scan

GitHub Code Quality doesn’t respect linguist-generated, [GeneratedCode] / [CompilerGenerated] attributes, filename patterns like *.g.cs, or custom include/exclude paths. Those work for Linguist and Code Scanning, but Code Quality currently analyzes all detected source files without configurable suppression for generated code.

If the warnings are coming from generated files, the only real workarounds today are excluding those files from the repo (or generating them in CI), moving them elsewhere, or using Code Scanning where path exclusions are supported.
