feat: Implement IPC backend for real-time UI synchronization

Add KiCAD IPC API backend using kicad-python library for real-time
communication with KiCAD 9.0+. Changes now appear instantly in KiCAD
UI without manual reload.

Key changes:
- Implement IPCBackend and IPCBoardAPI classes for IPC communication
- Auto-detect IPC availability and fall back to SWIG when unavailable
- Route existing commands (route_trace, add_via, place_component, etc.)
  through IPC automatically when available
- Add transaction support for proper undo/redo
- Add socket path auto-detection for Linux (/tmp/kicad/api.sock)

New commands:
- get_backend_info: Check which backend is active

Supported IPC operations:
- Board: set_size, get_board_info, save
- Routing: route_trace, add_via, add_net
- Components: place, move, delete, list
- Text: add_text, add_board_text

SWIG backend is now deprecated and will be removed when KiCAD 10.0
drops SWIG support.

Requires: kicad-python>=0.5.0, KiCAD 9.0+ with IPC enabled

# Changelog - 2025-11-30
## IPC Backend Implementation - Real-time UI Synchronization
This release implements the **KiCAD IPC API backend**, enabling real-time UI synchronization between the MCP server and KiCAD. Changes made through MCP tools now appear **instantly** in the KiCAD UI without requiring manual reload.
### Major Features
#### Real-time UI Sync via IPC API
- **Instant updates**: Tracks, vias, components, and text appear immediately in KiCAD
- **No reload required**: Eliminates the manual File > Reload workflow
- **Transaction support**: Operations can be grouped for single undo/redo steps
- **Auto-detection**: Server automatically uses IPC when KiCAD is running with IPC enabled
#### Automatic Backend Selection
- IPC backend is now the **default** when available
- Transparent fallback to SWIG when IPC unavailable
- Environment variable `KICAD_BACKEND` for explicit control:
- `auto` (default): Try IPC first, fall back to SWIG
- `ipc`: Force IPC only
- `swig`: Force SWIG only (deprecated)
#### Commands with IPC Support
The following commands now automatically use IPC for real-time updates:
| Command | Description |
|---------|-------------|
| `route_trace` | Add traces with instant UI update |
| `add_via` | Add vias with instant UI update |
| `add_text` / `add_board_text` | Add text with instant UI update |
| `set_board_size` | Set board size with instant outline update |
| `get_board_info` | Read live board data |
| `place_component` | Place components with instant UI update |
| `move_component` | Move components with instant UI update |
| `delete_component` | Delete components with instant UI update |
| `get_component_list` | Read live component list |
| `save_project` | Save via IPC |
### New Files
- `python/kicad_api/ipc_backend.py` - Complete IPC backend implementation (~870 lines)
- `python/test_ipc_backend.py` - Test script for IPC functionality
- `docs/IPC_BACKEND_STATUS.md` - Implementation status documentation
### Modified Files
- `python/kicad_interface.py` - Added IPC integration and automatic command routing
- `python/kicad_api/base.py` - Added routing and transaction methods to base class
- `python/kicad_api/factory.py` - Fixed kipy module detection
- `docs/ROADMAP.md` - Updated Week 3 status to complete
### Dependencies
- Added `kicad-python>=0.5.0` - Official KiCAD IPC API Python library
### Requirements
To use real-time mode:
1. KiCAD 9.0+ must be running
2. Enable IPC API: `Preferences > Plugins > Enable IPC API Server`
3. Have a board open in PCB editor
### Deprecation Notice
The **SWIG backend is now deprecated**:
- Will continue to work as fallback
- No new features will be added to SWIG path
- Will be removed when KiCAD 10.0 drops SWIG support
### Testing
Run the IPC test script:
```bash
./venv/bin/python python/test_ipc_backend.py
```
Or test individual commands:
```bash
echo '{"command": "get_backend_info", "params": {}}' | \
PYTHONPATH=python ./venv/bin/python python/kicad_interface.py
```
### Breaking Changes
None. All existing commands continue to work. IPC is used transparently when available.

# KiCAD IPC Backend Implementation Status
**Status:** 🟢 **FULLY INTEGRATED**
**Date:** 2025-11-30
**KiCAD Version:** 9.0.6
**kicad-python Version:** 0.5.0
---
## Overview
The IPC backend is now **fully integrated** as the **default backend** for all MCP tools. When KiCAD is running with IPC enabled, all commands automatically use real-time UI synchronization. Changes made through the MCP tools appear **instantly** in the KiCAD UI without requiring manual reload.
**SWIG backend is deprecated** and will be removed in a future version when KiCAD removes it (KiCAD 10.0).
## Key Benefits
| Feature | SWIG (Old) | IPC (New) |
|---------|------------|-----------|
| UI Updates | Manual reload required | **Instant** |
| Undo/Redo | Not supported | **Transaction support** |
| API Stability | Deprecated, will break | **Stable, versioned** |
| Connection | File-based | **Live socket connection** |
| Future Support | Removed in KiCAD 10.0 | **Official & maintained** |
## Implemented Features
### Automatic IPC Routing
The following MCP commands **automatically use IPC** when available:
| Command | IPC Handler | Real-time |
|---------|-------------|-----------|
| `route_trace` | `_ipc_route_trace` | Yes |
| `add_via` | `_ipc_add_via` | Yes |
| `add_net` | `_ipc_add_net` | Yes |
| `add_text` | `_ipc_add_text` | Yes |
| `add_board_text` | `_ipc_add_text` | Yes |
| `set_board_size` | `_ipc_set_board_size` | Yes |
| `get_board_info` | `_ipc_get_board_info` | Yes |
| `place_component` | `_ipc_place_component` | Yes |
| `move_component` | `_ipc_move_component` | Yes |
| `delete_component` | `_ipc_delete_component` | Yes |
| `get_component_list` | `_ipc_get_component_list` | Yes |
| `save_project` | `_ipc_save_project` | Yes |

## Usage
### Prerequisites
1. **KiCAD 9.0+** must be running
2. **IPC API must be enabled**: `Preferences > Plugins > Enable IPC API Server`
3. A board must be open in the PCB editor
### Installation
```bash
pip install kicad-python
```
### Basic Usage
```python
from kicad_api import create_backend
# Auto-detect and connect
backend = create_backend() # Will try IPC first, fall back to SWIG
backend.connect()
# Get board API
board = backend.get_board()
# Operations appear instantly in KiCAD UI!
board.add_track(
start_x=100.0, start_y=100.0,
end_x=120.0, end_y=100.0,
width=0.25, layer="F.Cu"
)
# With transaction support for undo
board.begin_transaction("Add components")
board.place_component("R1", "Resistor_SMD:R_0603", 50, 50)
board.place_component("C1", "Capacitor_SMD:C_0603", 60, 50)
board.commit_transaction("Added R1 and C1") # Single undo step
```
### Force Backend Selection
```python
# Force IPC backend
backend = create_backend('ipc')
# Force SWIG backend (deprecated)
backend = create_backend('swig')
# Or via environment variable
# export KICAD_BACKEND=ipc
```
## Testing
Run the test script to verify IPC functionality:
```bash
# Make sure KiCAD is running with IPC enabled and a board open
./venv/bin/python python/test_ipc_backend.py
```
The test script will:
1. Connect to KiCAD
2. List components on the board
3. Add a test track (visible instantly in UI)
4. Add a test via (visible instantly in UI)
5. Add test text (visible instantly in UI)
6. Read the current selection

```
## Known Limitations
1. **KiCAD must be running**: Unlike SWIG, IPC requires KiCAD to be open
2. **Project creation**: Must be done through KiCAD UI or file system
3. **Footprint library access**: Limited - best to use library management separately
4. **Layer management**: Layers are predefined in KiCAD
## Troubleshooting
### "Connection failed"
- Ensure KiCAD is running
- Enable IPC API: `Preferences > Plugins > Enable IPC API Server`
- Check if a board is open
### "kicad-python not found"
```bash
pip install kicad-python
```
### "Version mismatch"
- Update kicad-python: `pip install --upgrade kicad-python`
- Ensure KiCAD 9.0+ is installed
### "No board open"
- Open a board in KiCAD's PCB editor before connecting

└── swig_backend.py # Legacy SWIG wrapper

└── test_ipc_backend.py # IPC test script
```
## Future Enhancements
1. **Footprint library integration via IPC** - Load footprints directly
2. **Schematic IPC support** - When available in kicad-python
3. **Event subscriptions** - React to changes made in KiCAD UI
4. **Multi-board support** - Handle multiple open boards

Test script for KiCAD IPC Backend
This script tests the real-time UI synchronization capabilities
of the IPC backend. Run this while KiCAD is open with a board.
Prerequisites:
1. KiCAD 9.0+ must be running
2. IPC API must be enabled: Preferences > Plugins > Enable IPC API Server
3. A board should be open in the PCB editor
Usage:
