Oliver Kieselbach 8f24876682 feat(agent): live power-state watcher + battery analyze rules DEV-009/010
Event-driven AC/battery observation during enrollment (no polling): a WMI
Win32_PowerManagementEvent (EventCode 10) push subscription re-probes
GetSystemPowerStatus and diffs snapshots through a pure tracker into
power_state_change events - transition ac_to_battery (Warning, immediate) /
battery_to_ac (Info) / threshold_crossed at 50/30/15% (per-level lifetime
latch, lowest-crossed-only on jumps, arm-time baseline covers sessions
starting low, 5s trailing-edge debounce, emission cap 20). Never armed on
devices without a battery; arm failure surfaces as collector_degraded.
Kill-switch Collectors.EnablePowerStateWatcher (ConfigVersion 38).

power_state_change is classified non-activity on both sides
(SignalActivityClassifier + IsPeriodicOrStallEvent) so battery drain can
neither keep idle collectors alive nor heal a Stalled session.

New analyze rules, both with on_event:power_state_change interim triggers
and deliberately single-required-condition (event_data conditions scan
events independently - no same-instance join):
- ANALYZE-DEV-009 (high): thresholdPercent equals 15
- ANALYZE-DEV-010 (warning): transition equals ac_to_battery
