MA0110: Support top-level statements

[Copilot]

MA0110 (Use Regex Source Generator) now reports and fixes regex usage in top-level statements by generating a partial Program class.

Changes

• Fixer: Detect top-level statements by checking for null TypeDeclarationSyntax ancestor
• Fixer: Add ConvertTopLevelStatementToSourceGenerator to create or extend partial Program class at end of file
• Fixer: Handle GlobalStatementSyntax when removing local variable declarations in top-level contexts
• Fixer: Only infer member names from variable names when creating Regex objects, not for static method calls like Regex.IsMatch()
• Tests: Add 5 test cases covering partial methods, partial properties, and existing Program class scenarios

Example

Before:

using System.Text.RegularExpressions;

var emailRegex = new Regex("pattern");
emailRegex.Match("value");

After (C# 14 partial property):

using System.Text.RegularExpressions;
EmailRegex.Match("value");

partial class Program
{
    [GeneratedRegex("pattern")]
    private static partial Regex EmailRegex { get; }
}

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)
