Alex Cheema 7204fdeb4a Restore Thunderbolt Bridge LaunchDaemon (#1270) ...

## Motivation

The LaunchDaemon approach for disabling Thunderbolt Bridge was removed
in commit 43f12f5d and replaced with dynamic cycle detection. However,
the LaunchDaemon runs automatically on reboot, ensuring the bridge is
always disabled before it can cause packet storms.

## Changes

- Restore `NetworkSetupHelper.promptAndInstallIfNeeded()` to install a
LaunchDaemon that disables Thunderbolt Bridge on startup
- Show user prompt explaining what will be installed before requesting
admin password
- Remove old cleanup-only logic from `EXOApp.swift`
- Installer removes any existing installation before installing fresh
(handles upgrades)

## Why It Works

The LaunchDaemon runs at boot with `RunAtLoad=true` and periodically
(every ~30 min), destroying bridge0 and disabling Thunderbolt Bridge
before it can cause packet storms. The daemon is only installed
once—`daemonAlreadyInstalled()` checks script content and plist config
match before prompting.

## Test Plan

### Manual Testing
- Run app first time → should see prompt → click Install → enter admin
password → daemon installed
- Run app again → no prompt (already installed)
- Reboot → bridge0 should be destroyed/disabled automatically
- Check daemon: `launchctl list | grep io.exo.networksetup`
- Check files: `/Library/LaunchDaemons/io.exo.networksetup.plist`,
`/Library/Application Support/EXO/disable_bridge.sh`

### Automated Testing
N/A - requires admin privileges and system-level changes
