[Views2k]

A recovered run without a close request, a Windows fault or a Windows stop event was always shutdown-incomplete ("Wisp stopped without being closed" in Tools). On 2.7.x most of those runs ended on a PC that went to sleep or was locked and never came back, hiding the real unexplained stops among them.

What changed

• SessionEndSentinel now also handles WM_POWERBROADCAST (PBT_APMSUSPEND, PBT_APMRESUMEAUTOMATIC, PBT_APMRESUMESUSPEND) and WM_WTSSESSION_CHANGE (WTS_SESSION_LOCK, WTS_SESSION_UNLOCK, registered with WTSRegisterSessionNotification) on its own thread, and reports every notice through one SessionNotice callback. The shutdown notices keep their behaviour.
• The run marker records SuspendedAtUtc and SessionLockedAtUtc. Resuming and unlocking clear them; a checkpoint a minute or more after the sleep notice also clears it, because the checkpoint timer does not run while Windows sleeps. Invalid times (not UTC, before the run started) are dropped on read, so a marker from an earlier version keeps today's reading.
• PreviousRunRecovery sets RecoveredExitInfo.Suspended / SessionLocked from the previous marker when there is no fault, no native record, no Windows stop and no shutdown event. A matched fault clears both.
• The incident reason is system-sleep or session-locked (sleep wins when both are set); shutdown-incomplete remains for runs with neither state. Both reasons join the Reasons catalog (the Tools catalog was extended in Views2k/wisp-site first, since ingestion validates reasons).
• The local report names the state. Like a Windows shutdown, a run that ended on a sleeping or locked PC gets no card on the dashboard; the report stays in the store for the diagnostics bundle and Tools reporting.

Verified

• New unit tests: PreviousRunRecoveryTests (suspended / locked / both / neither reasons and report text; stop and shutdown events win; fault and recorded shutdown win), RunExitMarkerStoreTests (notices survive checkpoints and restart until withdrawn, invalid times rejected and dropped, late checkpoint clears sleep), SupplementaryIncidentCaptureTests (reason mapping and catalog validity), DiagnosticsViewModelCrashNoticeTests (no card). The PR gate selects these classes.
• dotnet format whitespace on the changed files; wisp-preflight. Windows build and tests run in CI.

Unverified

• Real sleep, hibernate, lock and resume on a Windows PC: that the sentinel window receives the notices, that the marker write completes before the PC sleeps, and that the next start labels the run. Needs a desktop check with Wisp running, separately on Steam and on the Xbox app / Microsoft Store build (the change is in the shared app code; neither platform's game path is touched).
• WTSRegisterSessionNotification on a PC where the Terminal Services service is stopped: the sentinel then records shutdowns and sleep only.
