monorepo: combine vpnhide-zygisk, vpnhide (lsposed), and vpnhide-kmod

Unified repository for the complete Android VPN-hiding stack:
- zygisk/ — Rust Zygisk module (inline libc hooks via shadowhook)
- lsposed/ — Kotlin LSPosed module (Java API + system_server hooks)
- kmod/ — C kernel module (kretprobe hooks, invisible to anti-tamper)

CI workflows use path filters to build only the changed component.
