v0.5.5-dev BETA

5tratumOS v0.5.5-dev BETA\n\nDEV-channel build of the Fleet telemetry reliability update.\n\n- Displays a positive live or adaptive per-worker hashrate when a short one-minute sample is temporarily zero.\n- Keeps the original hashrate windows available for diagnostics.\n- Expires disconnected ghost workers using last-share age instead of lingering rolling averages.\n- Keeps pool and worker cache ages independent so old worker snapshots cannot be refreshed indefinitely by pool totals.\n\nThis does not alter 5TRAT consensus, wallets, balances, mining difficulty or pool rewards.
