Add real-time GC log monitoring via argus gclog --follow/-f: - GcLogFollower: tails growing GC log files via RandomAccessFile, incremental parsing of new lines with format auto-detection - GcLogPatterns: shared regex patterns extracted for reuse - RollingGcAnalysis: circular buffer with live metrics snapshot (percentiles, throughput, Full GC tracking, events/sec) - GcLogCommand --follow: live-updating terminal display with 2-second refresh, Ctrl+C to quit Signed-off-by: rlaope <piyrw9754@gmail.com>
