feat: Three-tier API Architecture (v2.2.0) 

NEW: core/api/ directory with comprehensive three-tier API

PluginAPI (core/api/plugin_api.py):
- 12 core service integrations (Log, Window, OCR, Screenshot, Nexus, HTTP, Audio, Notifications, Clipboard, Event Bus, Data Store, Tasks)
- Full docstrings with examples for every method
- Thread-safe design with Qt signal marshaling
- Proper error handling with custom exceptions
- Service availability checking

WidgetAPI (core/api/widget_api.py):
- Widget creation and management
- WidgetConfig dataclass for configuration
- WidgetType enum (MINI, CONTROL, CHART, ALERT, CUSTOM)
- WidgetAnchor enum for positioning
- Event system (moved, resized, closing, closed, update)
- Layout helpers (grid, horizontal, vertical, cascade)
- Persistence (save/load widget states)
- Widget presets for reuse

ExternalAPI (core/api/external_api.py):
- REST API server with aiohttp
- API endpoint registration (decorator and programmatic)
- Incoming webhooks with HMAC verification
- Outgoing webhook POST support
- API key authentication
- IPC (inter-process communication)
- File watcher for config changes
- Server-Sent Events (SSE) support
- CORS configuration
- Webhook history tracking

core/api/__init__.py:
- Unified imports for all three APIs
- Version tracking (2.2.0)
- Clean namespace exports

docs/API_REFERENCE.md:
- Comprehensive 12,000+ word reference
- Quick start examples for each API
- Service-by-service documentation
- Error handling guide
- Integration examples (Discord, custom widget)

Integration:
- Updated core/main.py to import from new API structure
- All three APIs available via: from core.api import get_api, get_widget_api, get_external_api

Benefits:
- Clear separation of concerns (plugins vs widgets vs external)
- Well-documented APIs for developers
- Easy to extend with new services
- Type hints throughout
- Production-ready error handling
- Third-party integration support out of the box

EU-Utility - Core APIs
======================
A comprehensive three-tier API architecture for EU-Utility.
Three APIs:
-----------
1. PluginAPI (core.api.plugin_api) - For plugin development
2. WidgetAPI (core.api.widget_api) - For widget management
3. ExternalAPI (core.api.external_api) - For external integrations
Quick Reference:
---------------
PluginAPI - Access core services:
>>> from core.api import get_api
>>> api = get_api()
>>> api.show_notification("Hello", "World!")
>>> window = api.get_eu_window()
WidgetAPI - Manage overlay widgets:
>>> from core.api import get_widget_api
>>> widget_api = get_widget_api()
>>> widget = widget_api.create_widget("tracker", "Loot Tracker")
>>> widget.show()
ExternalAPI - Third-party integrations:
>>> from core.api import get_external_api
>>> ext = get_external_api()
>>> ext.start_server(port=8080)
>>> ext.register_webhook("/discord", handler)
See individual API modules for full documentation.

EU-Utility - External API
================
The ExternalAPI provides interfaces for third-party integrations,
webhooks, REST endpoints, and external application communication.
This API is designed for:
- Browser extensions
- Discord bots
- Home Assistant
- Stream Deck
- Custom scripts
- Other applications
Quick Start:
-----------
```python
from core.api.external_api import get_external_api
# Start the REST API server
api = get_external_api()
api.start_server(port=8080)
# Register a webhook handler
api.register_webhook("/loot", handle_loot_event)
# Send data to external service
api.post_webhook("https://discord.com/webhook/...", {"content": "Hello!"})
```
Integration Types:
-----------------
- REST API - HTTP endpoints for external queries
- Webhooks - Receive events from external services
- WebSocket - Real-time bidirectional communication
- IPC - Inter-process communication
- File Watch - Monitor file changes

EU-Utility - Plugin API
================
The PluginAPI provides plugins with access to core services and functionality.

```
Services Available:
------------------
- Log Reader - Read game chat.log
- Window Manager - Get EU window info, focus control
- OCR Service - Screen text recognition
- Screenshot - Capture screen regions
- Nexus API - Item database queries
- HTTP Client - Web requests with caching
- Audio - Play sounds
- Notifications - Toast notifications
- Clipboard - Copy/paste operations
- Event Bus - Pub/sub events
- Data Store - Key-value storage
- Tasks - Background task execution

EU-Utility - Widget API
================
The WidgetAPI provides a comprehensive interface for creating, managing,
and interacting with overlay widgets.
Widgets are floating, draggable UI components that appear over the game.
They can display real-time data, controls, or mini-versions of plugins.
Quick Start:
-----------
```python
from core.api.widget_api import get_widget_api
class MyPlugin(BasePlugin):
def initialize(self):
self.widget_api = get_widget_api()
def create_widget(self):
widget = self.widget_api.create_widget(
name="my_widget",
title="My Widget",
size=(300, 200)
)
widget.show()
```
Widget Types:
------------
- MiniWidget - Small info display
- ControlWidget - Interactive controls
- ChartWidget - Data visualization
- AlertWidget - Notifications/overlays
