Implement configurable system volume following and replace JSON IPC with binary struct. - New Feature: Introduce `system_volume_following` CLI and runtime option. - Enhancement: Extend CLI options, reload, and user‑config APIs to propagate the new flag. - Enhancement: Add `VbxEvent` binary IPC struct and logging macros for better performance. - Enhancement: Add helper to persist system volume following state. - Bug Fix: Remove stale `parse_keyboard_event` prototype.
