New Programs

• pstat: Monitor a macOS process's CPU, memory, thread, context-switch,
  and energy usage.

Improvements

  resolution through hwdata.
• zfetch: Show monitor refresh rates and identify built-in displays in
  resolution output.
• zfetch: Improve shell detection and reading of /proc and theme files.

  dedicated C module, fixing builds affected by Mach, IOKit, and libproc

Bug Fixes

• zfetch: Fix memory leaks in macOS display enumeration and prevent
  underflow in macOS memory accounting.
• zfetch: Explicitly link libc for the macOS implementation.
