Razor Formatting Log Investigation

Use this skill when:

investigating a Razor formatting issue from Visual Studio or VS Code feedback
given an Azure DevOps work item, Developer Community ticket, or GitHub issue that includes a formatting log zip
asked to import a Full_*_razor.zip or Range_*_razor.zip archive into the test suite

Goal

Get a local path to the formatting log archive.
Import every file from that zip into src\Razor\src\Razor\test\Microsoft.VisualStudio.LanguageServices.Razor.UnitTests\TestFiles\FormattingLog\<TestName>\.
Add a matching [Fact] to src\Razor\src\Razor\test\Microsoft.VisualStudio.LanguageServices.Razor.UnitTests\Cohost\Formatting\FormattingLogTest.cs.
Run the imported formatting log test.
If it passes, report that the issue captured in the logs no longer reproduces.
If it fails, keep the imported repro, reduce it to a minimal DocumentFormattingTest, and then fix the product code.
