Process Resource Growth Watcher is a desktop time-series process resource telemetry and baseline delta analyzer for Linux. An independent Linux utility inspired by GDIView, it samples /proc/<pid>/status, /proc/<pid>/statm, /proc/<pid>/fd, and /proc/<pid>/maps across time to compare live process resource usage against a captured baseline and spot sustained memory, handle, memory-mapping, or thread growth.

Key Features:

• Baseline vs Live Delta Matrix: Tracks VmRSS, RssAnon, VmSize, open file descriptor count, virtual memory mapping (VMA) count, and thread count per PID, computing net +KB / +FD deltas and linear growth slopes across captured snapshots.
• Multi-PID Growth Trajectory Charts: Plots real-time multi-process VmRSS and open file descriptor curves across recorded samples in both absolute and baseline-delta views alongside per-snapshot tabular history.
• Kernel Handle & VMA Breakdown: Classifies open file descriptors for any accessible process into Regular Files, Sockets, Pipes, Anonymous Inodes (epoll, eventfd, timerfd, inotify), Shared Memory / Memfd / DRM nodes, and Character Devices, paired with a virtual memory area (heap, stack, shared libraries, anonymous mappings) inspector.
• Structured Telemetry Export: Exports process delta rankings and time-series snapshot logs to CSV and JSON files.
