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

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.

Start by reproducing dotnet fsharplint lint Tests.fsproj with project.assets.json in both the test project's and dependency's obj/ directories, then compare it with wildcard mode and with those files removed. The issue names no repository files or tests; done means project-mode lint completes without hanging while wildcard behavior remains unchanged.
