Add LSPosed interception stats

[okhsunrog]

Summary

• add LSPosed Java/app-hiding hook ids to the shared hook registry and regenerated C/Rust/Kotlin ids
• replace the old /data/system/vpnhide_hook_active heartbeat with one /data/system/vpnhide_lsposed_state readback file carrying vpnhide 1 status plus vpnhide 1 stats
• record successful LSPosed result mutations per caller UID and hook id, and include the state file in dashboard/root snapshot and diagnostics
• keep native JSON hook-list projection bounded to kernel-owned hook ids

Stacked on #174.

Validation

• cd lsposed && ./gradlew :app:testDebugUnitTest :app:ktlintCheck :app:detekt cpdCheck
• cargo fmt --check && cargo test -p vpnhide_activator -p vpnhide_protocol
• python3 scripts/codegen-hooks.py idempotence check over generated hook id files
• make -C kmod kpm
• host C protocol/logic tests (test_iface_lists, test_vpnhide_logic, test_protocol)
• git diff --check
