Increment 2: deep per-process data + process inspector

- ProcessItem: disk read/write rate + cumulative bytes, energy-impact score,
  executable path; equality now tracks energy/disk so the table refreshes
- ProcessMonitor: disk I/O + idle-wakeup rates from rusage_info_v4; full path
  capture; on-demand KERN_PROCARGS2 args + PROC_PIDLISTFDS open-file count
- EnergyModel heuristic + pure ProcArgs parser (both unit-tested)
- ProcessView: sortable Energy + Disk I/O columns (icon folded into Name to stay
  within SwiftUI's 10-column limit); Get Info (double-click / ⌘I) opens inspector
- ProcessInspectorSheet: live stats, path, args, open files, Reveal/Copy Path
- 10 new tests (32 total green); smoke: stable under CPU+disk load
