Service:
- Build complete LoopContext in Windows service runAgent (was missing
ReceiptTracker, ConfirmedTracker, scanners, circuit breakers,
kernel enforcer — nil ReceiptTracker caused immediate panic).
- Wire process logger so log.Printf writes to agent.log on Windows.
- Parse CPU info JSON from PowerShell fallback (wmic absent on
modern Windows; old code tried CSV parse on JSON output).
Local state cache:
- Agent writes status, scan results, capability token state to
local disk cache. Enables local observability without a server
round-trip. Handlers expose /local/state, /local/status endpoints.
- Record agent status (online/backoff) and capability token metrics
to local cache during polling loop.
