This adds COUNTER_VALUE, GAUGE_VALUE, and HISTOGRAM_VALUE macros that allow reading metric values directly as native types (int64_t for counters/gauges, HistogramStatistics struct for histograms) without going through JSON serialization. Also made gather_result() public to allow custom metric collection without JSON if needed. Tests added to farm_test.cpp verify the new direct access methods work correctly across all metric types.
