Implement Kitty graphics protocol for background image rendering

- Added `kitty_gfx` module to handle loading, scaling, and displaying background images using the Kitty graphics protocol.
- Integrated background image handling into the main application loop, allowing dynamic updates based on configuration.
- Enhanced terminal rendering to support transparent backgrounds when a Kitty image is active.
- Updated IPC server to manage client connections and messages, including handling background image settings.
- Modified `PtyTerminal` to accept additional environment variables during shell spawning.
- Improved rendering logic to support popup dialogs and terminal background color customization.

---
## Startlägen
TUI-WM kan startas i tre lägen:
### Standalone (standard)
```bash
tui-wm
```
Kör fönsterhanteraren i den aktuella terminalen och startar samtidigt en Unix-socket-server. Andra program kan ansluta till socketen medan TUI-WM kör.
### Daemon (`-d`)
```bash
tui-wm -d
```
Kör headless — ingen lokal terminal-rendering. State hanteras enbart via socketen. Frames renderas internt och skickas till anslutna display-klienter. Passar för att köra TUI-WM som bakgrundstjänst.
### Klient (`-c`)
```bash
tui-wm -c [socket-sökväg]
```
Ansluter till en befintlig TUI-WM-server (standalone eller daemon) som display-klient. Renderar mottagna frames och vidarebefordrar tangentbords- och resize-events. Om `socket-sökväg` utelämnas används standard-sökvägen. Koppla ned med **Ctrl+Shift+Q**.
---
## Socket-API
Appar som körs inne i TUI-WM får miljövariablerna `TUI_WM_SOCKET` (sökväg till socketen) och `TUI_WM_WINDOW_ID` (fönstrets ID) satta automatiskt. Via socketen kan de:
- Spawna nya terminalfönster
- Visa popup-dialoger med knappar och vänta på svar
- Lista eller stänga fönster
- Ta emot renderade frames (ANSI) för att visa TUI-WM:s skärm
Se [SOCKET_API.md](SOCKET_API.md) för fullständig protokolldokumentation med JSON-exempel och kodexempel i Bash och Python.

# TUI-WM Socket API
TUI-WM exposes a Unix domain socket that allows other applications to interact with the window manager: spawn windows, show popup dialogs, list or close windows, and receive rendered frames.
## Overview
The protocol uses a simple framing format: every message is preceded by a 4-byte big-endian `u32` indicating the byte length of the JSON payload, followed by the JSON itself.
```
[ 4 bytes: length (big-endian u32) ][ N bytes: JSON ]
```
All messages are JSON objects with a mandatory `"type"` field (snake_case) that discriminates the message kind.
## Connecting
### Environment variables
When TUI-WM spawns a terminal inside a window it sets two environment variables for the child process:
| Variable | Example value | Description |
|-------------------|----------------------------|------------------------------------------|
| `TUI_WM_SOCKET` | `/run/user/1000/tui-wm.sock` | Path to the Unix socket |
| `TUI_WM_WINDOW_ID`| `3` | The window ID of the containing window |
### Finding the socket path
If the environment variables are not set (e.g. you are connecting externally), the socket is located at:
- `$XDG_RUNTIME_DIR/tui-wm.sock` (preferred)
- `/tmp/tui-wm-$USER.sock` (fallback)
- `/tmp/tui-wm.sock` (last resort)
### Client roles
Every client must identify itself as one of two roles in the initial `hello` message:
- **`display`** — receives rendered frames (ANSI) from the server and forwards input back.
- **`app`** — sends commands to the window manager (spawn windows, show popups, etc.) and receives responses.
A client can act as both simultaneously by choosing either role; `display` clients will receive `frame` messages in addition to any command responses.
## Handshake
Every connection must begin with a `hello` message. The server replies with `hello_ok`.
### Client → Server: `hello`
```json
{
"type": "hello",
"role": "display",
"width": 220,
"height": 50,
"window_id": null
}
```
| Field | Type | Required | Description |
|-------------|-----------------|----------|---------------------------------------------------|
| `role` | `"display"` \| `"app"` | Yes | Client role |
| `width` | integer (u16) | Yes | Client terminal width (used for frame sizing) |
| `height` | integer (u16) | Yes | Client terminal height |
| `window_id` | integer \| null | No | The window ID from `TUI_WM_WINDOW_ID` if available |
### Server → Client: `hello_ok`
```json
{
"type": "hello_ok",
"version": "0.1.0",
"socket_path": "/run/user/1000/tui-wm.sock"
}
```
## Client → Server messages
### `input`
Forward raw terminal input bytes to the focused window. Bytes are hex-encoded.
```json
{ "type": "input", "data": "1b5b41" }
```
The example sends the bytes `0x1b 0x5b 0x41` (Up arrow).
### `resize`
Notify the server that the display client's terminal has been resized.
```json
{ "type": "resize", "width": 200, "height": 48 }
```
### `spawn_window`
Ask the server to open a new terminal window running the given command.
```json
{
"type": "spawn_window",
"command": "/bin/bash",
"request_id": "req-1"
}
```
The server responds with `window_opened`.
### `spawn_popup`
Show a modal popup dialog with a message and configurable buttons. The server responds with `popup_result` once the user dismisses the dialog.
```json
{
"type": "spawn_popup",
"message": "Vill du avsluta?",
"buttons": ["Ja", "Nej"],
"request_id": "req-2"
}
```
If `buttons` is omitted it defaults to `["Ja", "Nej"]`.
### `list_windows`
Request a list of all open windows.
```json
{ "type": "list_windows", "request_id": "req-3" }
```
### `close_window`
Close the window with the given ID.
```json
{ "type": "close_window", "window_id": 3, "request_id": "req-4" }
```
### `set_background`
Set or remove the desktop background image (requires Kitty graphics protocol support in the host terminal).
```json
{ "type": "set_background", "path": "/path/to/image.jpg", "save": true, "request_id": "req-5" }
```
- `path` — Path to image file (JPEG/PNG/GIF/BMP/WebP), or `null` to remove the background.
- `save` — If `true`, the change is persisted to `config.toml`.
## Server → Client messages
### `hello_ok`
See handshake section above.
### `frame`
Sent to `display` clients every render cycle (~60 fps). The `data` field is a hex-encoded ANSI escape sequence string that, when written to a terminal, renders the full current state of the TUI-WM screen.
```json
{
"type": "frame",
"width": 200,
"height": 48,
"min_width": 200,
"min_height": 48,
"data": "1b5b306d1b5b324a..."
}
```
To display a frame, decode `data` from hex and write the raw bytes to stdout.
### `window_opened`
Response to `spawn_window`.
```json
{
"type": "window_opened",
"id": 5,
"request_id": "req-1"
}
```
### `popup_result`
Response to `spawn_popup` — sent when the user selects a button or presses Escape.
```json
{
"type": "popup_result",
"button": "Ja",
"button_index": 0,
"request_id": "req-2"
}
```
### `window_list`
Response to `list_windows`.
```json
{
"type": "window_list",
"windows": [
{ "id": 1, "x": 2, "y": 2, "width": 82, "height": 26, "title": "bash" },
{ "id": 3, "x": 6, "y": 4, "width": 82, "height": 26, "title": "nvim" }
],
"request_id": "req-3"
}
```
### `error`
Sent when a request cannot be fulfilled.
```json
{
"type": "error",
"message": "Window not found",
"request_id": "req-4"
}
```
## Code examples
### Bash — show a popup and read the result
```bash
#!/usr/bin/env bash
SOCKET="${TUI_WM_SOCKET:-/tmp/tui-wm.sock}"
# Build the hello + spawn_popup messages
send_msg() {

local len=${#json}
# Write 4-byte big-endian length followed by JSON
printf "$(printf '\\x%02x\\x%02x\\x%02x\\x%02x' \
$((len >> 24 & 0xff)) $((len >> 16 & 0xff)) \
$((len >> 8 & 0xff)) $((len & 0xff)))"
printf '%s' "$json"
}
{
send_msg '{"type":"hello","role":"app","width":80,"height":24}'
send_msg '{"type":"spawn_popup","message":"Continue?","buttons":["Yes","No"],"request_id":"r1"}'
} | nc -U "$SOCKET" | python3 -c "

## Operating modes
TUI-WM can be started in three modes:
### Standalone (default)
```
tui-wm
```
Runs the full TUI window manager in the current terminal and simultaneously starts a Unix socket server. Other applications can connect to the socket while TUI-WM is running.
### Daemon (`-d`)
```
tui-wm -d
```
Runs headless — no terminal rendering. State is managed entirely via the socket. Frames are rendered to an internal buffer and sent to any connected `display` clients. Ideal for running TUI-WM as a background service.
### Client (`-c`)
```
tui-wm -c [socket-path]
```
Connects to an existing TUI-WM server (standalone or daemon) as a display client. The client renders received frames and forwards keyboard/resize events to the server. If `socket-path` is omitted, the default path is used. Disconnect with **Ctrl+Shift+Q**.

//! Kitty graphics protocol — bakgrundsbildrendering.

//! 3. Transmittera som PNG via APC escape-sekvenser
//! 4. Visa med negativ z-index (under text)

//! Bilden tilldelas image-id 1 och placement-id 1.
