Oliver Kieselbach e1b03de5b3 fix(agent): recover ESP completion after a forced mid-ESP reboot
Seven sits-d Cloud PCs enrolled the same day with identical configuration
(~138 required apps at the user-ESP gate, DeviceGuard/DmaGuard device-assigned).
The two that finished AccountSetup before the coalesced reboot landed succeeded;
the five the reboot killed in Stage=EspAccountSetup never derived a completion
again and ended Incomplete on healthy devices. Two defects behind that:

ShellCoreTracker.BackfillRecentEspExitEvents() has existed since session
772fe502 but no caller ever invoked it, so the Shell-Core watcher only saw
records written after Start(). Every agent restart silently dropped an ESP exit
(62407) or Hello-wizard start (62404) from its downtime. EspAndHelloHost.Start()
now calls it, and the fixed 5-minute window is sized to the actual downtime when
the previous run died to a reboot (LastBootUtc, clamped to 360 min).

The user-apps-settled synthesis ran only on the EspExited edge. When the ESP page
exits with apps still in flight the single attempt misses and nothing re-checks —
8110e262 and a89aac2d both reached 138/138 apps, 0 failed, and still never
completed. The exit edge is now recorded and the synthesis re-evaluated from
ImeLogTracker.OnAppStateChanged. No new completion path: the gate conditions are
unchanged, this only gives the existing conservative check a second look. The
fire-once claim moves to Interlocked (edge and re-check run on different threads)
and the re-check does not re-emit app_install_starved.

Rules: ANALYZE-ESP-005 gains on_event:session_stalled so a hung session produces
a finding at the 60-minute stall instead of staying finding-less for hours
(verified against 8110e262 — fired, confidence 95). New ANALYZE-APP-016 turns the
already-emitted app_install_starved events into a customer finding and, unlike
ANALYZE-APP-015, fires even on a succeeded session: 3b9291aa was recorded
Succeeded with 99 required apps that never started installing.

ANALYZE-APP-015 and ANALYZE-ESP-001 were considered for the stall trigger and
deliberately left alone — APP-015 is the documented worked example of the
terminal-precondition trap, and ESP-001's phase_duration gate on a still-open
phase is unverified mid-run.
