Pull Request Overview

Adds WireGuard interface statistics to the debug bundle by introducing a FullStats method across the interface layers and wiring its output into the debug generator.

• Define a new WGIfaceStatus interface and expose it via Status.PeersStatus()
• Implement FullStats() for all WireGuard backends (kernel, userspace, configurer)
• Generate and include a wg show–style output in the debug archive

client/iface/configurer/usp.go:22

• [nitpick] This constant lacks the ipcKey prefix used by other IPC-related keys, which may confuse readers. Consider renaming to ipcKeyPrivateKey.

privateKey                  = "private_key"

client/internal/peer/status.go:1050

• [nitpick] The error message references the internal variable name wgInterface. It would be clearer to say something like "WireGuard interface not set".

return nil, fmt.Errorf("wgInterface is nil, cannot retrieve peers status")

client/internal/peer/status.go:35

• [nitpick] The name WGIfaceStatus mixes abbreviations and may be unclear; consider WireGuardInterfaceStatus or WGInterfaceStatsProvider for clarity.

type WGIfaceStatus interface {
