A focused capture that ends without a clean stop (no session-stop, no live
recorder) is treated as a likely hard freeze.
- core/diagnostic.py: pending_crash() detects the unterminated session;
acknowledge_crash() dismisses it; analyze_crash() combines the captured window
(final readings + GPU-lost) with a focused scan of the PREVIOUS (crashed) boot
+ SMART/driver/persistence/temps.
- health.check_previous_boot() scans `journalctl -k -b -1`; run_health_checks
gained include_journal to avoid double-scanning for the crash path.
- GUI: Games page shows a warning banner on launch for an interrupted diagnostic
with Analyze crash / Dismiss → results dialog.
- Tests for crash detection / clean-stop / acknowledge / in-progress.
