Wrap freenet release binary in a minimal .app bundle for macOS menu bar testing

wrap-freenet-app.sh

#!/bin/bash
# Wrap the built freenet binary in a minimal .app bundle so macOS will let it
# register a menu bar icon. Run this from the freenet-core repo root after
# `cargo build --release -p freenet` has produced target/release/freenet.
#
# Output: ./Freenet.app — launch with `open Freenet.app`.
