#### Open file descriptor, kernel lock & socket inspector for Linux

Process Handle Inspector is a desktop open file descriptor, kernel file lock, and
socket endpoint viewer for Linux system administration and application debugging.
An independent Linux alternative inspired by command-line handle and lsof utilities,
it reads live /proc descriptor tables, /proc/locks, and /proc/net socket tables to
reveal which files, pipes, event loops, locks, and sockets are held by running processes.

Key Features:

* Live Process File Descriptor Table: Enumerates accessible /proc/<pid>/fd links and
  /proc/<pid>/fdinfo flags (O\_RDONLY, O\_WRONLY, O\_RDWR, O\_APPEND, O\_CLOEXEC, file offset,
  and mount ID) across running user and readable system processes.
* Socket Inode Cross-Reference: Maps socket:[inode] handles directly against live
  /proc/net/tcp, /proc/net/tcp6, /proc/net/udp, /proc/net/udp6, and /proc/net/unix
  tables to show local/remote IP:port endpoints, TCP states, and UNIX domain paths.
* Kernel File Locks & Unlinked Files: Inspects active POSIX, FLOCK, and OFD locks in
  /proc/locks and highlights open (deleted) unlinked files still occupying disk space.
* Descriptor Breakdown & Ulimit Telemetry: Renders an open descriptor category chart,
  tracks per-process FD soft/hard limits (/proc/<pid>/limits), and exports CSV and JSON reports.
