Gud Boi b1f372bad1 Isolate `Qt` tests from process state ... Own XDG config roots before Piker or Qt imports and restore the caller's process environment when pytest exits. Also, - force offscreen rendering through an explicit `--headless` flag - restore QSettings, config globals and PyQtGraph registries per test - prove one QApplication can serve repeated tests without state leaks - document each teardown phase and a future public config-path API (this patch was generated in some part by `opencode` using `gpt-5.6-sol` (`openai`))		2026-08-31 22:11:27 -04:00
