Align GTK app with Apple home surface
Add the GTK home screen, local account store, daemon gRPC wrapper, and embedded Linux daemon startup path so the Linux app follows the Apple client UX and daemon boundary.

Document the GTK parity expectations and update the daemon IPC and Tailnet BEPs with the cross-platform client model.

# Linux GTK App Getting Started
Currently, the GTK App can be built as a binary or as an AppImage.
Note that the flatpak version can compile but will not run properly!
## Dependencies
### Install Build Dependencies
<details>
<summary>Debian</summary>
> Note: Burrow currently cannot compile on Debian Stable (Bookworm) due to its outdated dependencies
1. Install build dependencies

sudo apt install -y clang meson cmake pkg-config libssl-dev libgtk-4-dev libadwaita-1-dev gettext desktop-file-utils
```
2. Install flatpak builder (Optional)
```
sudo apt install -y flatpak-builder
```
3. Install AppImage build tools (Optional)
```
sudo apt install -y wget fuse file
```
</details>

</details>
<details>
<summary>Void Linux (glibc)</summary>
1. Install build dependencies

sudo xbps-install -Sy gcc clang meson cmake pkg-config openssl-devel gtk4-devel gettext desktop-file-utils gtk4-update-icon-cache appstream-glib
```
2. Install flatpak builder (Optional)
```
sudo xbps-install -Sy flatpak-builder
```
3. Install AppImage build tools (Optional)
```
sudo xbps-install -Sy wget fuse file
```
</details>
### Flatpak Build Dependencies (Optional)
```
flatpak install --user \
org.gnome.Platform/x86_64/45 \
org.freedesktop.Sdk.Extension.rust-stable/x86_64/23.08
```
## Building
With Nix, enter the focused GTK shell before running the Meson build:
```bash
nix develop .#gtk
```
<details>
<summary>General</summary>
1. Enter the `burrow-gtk`
```bash
cd burrow-gtk
```
2. Perform the meson build
```
meson setup build
meson compile -C build
```
</details>
<details>
<summary>Flatpak</summary>
1. Compile and install the flatpak
```
flatpak-builder
--user --install --force-clean --disable-rofiles-fuse \
flatpak_debug/ \
burrow-gtk/build-aux/com.hackclub.burrow.devel.json
```
</details>
<details>
<summary>AppImage</summary>
1. Enter the `burrow-gtk`
```bash
cd burrow-gtk
```
2. Compile the AppImage
```
./build-aux/build_appimage.sh
```
</details>
## Running
The GTK app mirrors the Apple home surface: a Burrow header, Networks carousel,
Accounts section, Tunnel action, and the same add flows for WireGuard, Tor, and
Tailnet. It talks to the daemon over the same gRPC API used by Apple clients for
network storage, tunnel state, Tailnet discovery, authority probing, browser
sign-in, and Tailnet payloads.
On Linux the GTK app first looks for a daemon on the configured gRPC socket. If
none is reachable, it starts an embedded user-scoped daemon with a socket under
`XDG_RUNTIME_DIR` and a database under `XDG_DATA_HOME` before refreshing the UI.
