Ambient LLM environment variables can append -tlp:DISABLENODEDISPLAY, causing exact MSBuild invocation assertions to fail intermittently.

• Invocation assertions

  • Normalize the environment-dependent terminal logger argument before comparing command shapes.
  • Apply normalization consistently across exact build, clean, MSBuild, publish, and store assertions.

• LLM detection coverage

  • Share the complete detector environment-variable list.
  • Clear and restore all detector inputs so positive and negative cases are isolated from the host environment.

Production CLI behavior is unchanged.

• Fixes CA CLI invocation tests flake on Mac arm64 Helix due to -tlp:DISABLENODEDISPLAY leaking through AdjustMSBuildForLLMs #56258

@copilot #56258 (comment) has a good question. Check to see if there is an avoidable (or isolatable) environment change to the variable.

Addressed in ee042c1. The avoidable change came from two parallel in-process detector tests, not Helix setup. They now run with DoNotParallelize, and I removed the argument-normalization workaround so invocation assertions remain strict.

@JeremyKuhne I think I might have a better fix..one sec.
