util/sys/sys_linux.go:
- GetTCPCount/GetUDPCount were counting the column header row in
/proc/net/{tcp,udp}[6] as a connection, inflating the reported total
by 1 per non-empty file (so the panel status line always showed 2
more connections than actually existed). Replace getLinesNum +
safeGetLinesNum with a single bufio.Scanner-based countConnections
that skips the header.
- CPUPercentRaw now opens HostProc("stat") instead of a hardcoded
/proc/stat so HOST_PROC overrides apply, matching the connection
counters in the same file.
- Simplify CPU field unpacking: pad nums to 8 once instead of guarding
every assignment with a len check.
util/sys/sys_darwin.go:
- Fix swapped idle/intr indices on kern.cp_time. BSD CPUSTATES order
is user, nice, sys, intr, idle (CP_INTR=3, CP_IDLE=4) — gopsutil's
cpu_darwin_nocgo.go reads the same layout. The previous code used
out[3] as idle and out[4] as intr, so busy = total - dIdle was
actually subtracting interrupt time, making the panel report CPU
usage close to 100% on macOS regardless of actual load.
- Collapse the per-field delta math into a single loop.

Three Windows-specific issues addressed:
1. Orphaned xray-windows-amd64 after VS Code debugger stop. Delve's
"Stop" sends TerminateProcess to the Go binary, which is uncatchable
— our signal handlers never run, so xrayService.StopXray() is skipped
and xray is left dangling. Spawn xray as a child of a Job Object with
JOB_OBJECT_LIMIT_KILL_ON_JOB_CLOSE so the OS kills xray when our
handle to the job is closed (which happens even on TerminateProcess).
Also trap os.Interrupt in main so Ctrl+C in the terminal runs the
graceful path.
2. /panel/setting/restartPanel logged "failed to send SIGHUP signal: not
supported by windows" because Windows can't deliver arbitrary signals.
Add a restart hook in web/global; main registers it to push SIGHUP
into its own signal channel, and RestartPanel calls the hook before
falling back to the (Unix-only) signal path. Same restart-loop code
runs in both cases.
3. util/sys/sys_windows.go now uses windows.NewLazySystemDLL so the
kernel32.dll resolve is pinned to %SystemRoot%\System32 (prevents
DLL hijacking by a planted DLL next to the binary). Local filetime
type replaced with windows.Filetime, and the unreliable
syscall.GetLastError() fallback replaced with a type assertion on the
errno captured at call time.
