Initial commit — FlipperDroid v0.1.0-poc

KernelSU module + Flipper Zero FAP that bridges both devices into a unified pentesting platform over USB CDC serial / BT rfcomm. Android side: bridge daemon, WebUI (:8089), bind mount namespace isolation stealth engine. Flipper side: proper FAP with 4-view GUI, GPIO/SubGHz/IR/file command handlers, async event streaming.
