bug: Project-mode lint hangs when project.assets.json exists in obj/ directories

[michaelglass]

dotnet fsharplint lint Tests.fsproj hangs indefinitely on one project in my repo. The problem surfaced after extracting code from one project into a sibling project. I haven't put in the effort to reproduce it outside my project, but the behavior is 100% reproducible in my closed-source codebase.

• Hangs with project.assets.json present in obj/ dirs
• Completes in ~23s after removing project.assets.json from both the test project and its library dependency (removing from only one is not sufficient)
• Wildcard mode (Tests/**/*.fs) works fine regardless
• dotnet build-server shutdown, DOTNET_CLI_DO_NOT_USE_MSBUILD_SERVER=1, MSBUILDDISABLENODEREUSE=1 don't help

Environment: FSharpLint 0.26.10, .NET 10.0, macOS ARM64

Workaround: Temporarily move project.assets.json out of obj/ dirs before linting, restore after.

Happy to share more project structure details if helpful.
