Pester 6 Fixes (Copilot-generated)

Fix #2657: Clear-TestDrive performance

Clear-TestDrive was extremely slow with many files because it called Remove-Item on every individual file. Replaced with HashSet-based approach that only calls Remove-Item -Recurse on root new items.

Fix #2649: NUnit3 ToString crash protection

NUnit3 report writing crashed when a test output object's ToString() method throws. Wrapped in try/catch with a descriptive fallback string.

All 2154 tests pass locally.

Superseded by individual PRs per review feedback. Each fix now has its own PR (#2689-#2697).
