Add documentation for modules and runtime instructions

- Created detailed documentation for the device_manager, model, model_extra, osc, overlay, overlay_image, transcription, translation, transliteration, utils, watchdog, and websocket modules.
- Added a comprehensive run events payloads document outlining the payloads sent during various run events in the controller.
- Included runtime instructions and dependencies for setting up the project in a Windows environment.
- Introduced a mypy configuration file to manage type checking and ignore errors in specific modules temporarily.

+## サンプル（呼び出し例）
+
+以下は Model の簡単な呼び出し例です。
+
+```python
+from model import model
+
+# マイク転写のコールバック例
+def on_mic_result(result: dict):
+    # result の想定形: {"text": str|False, "language": str}
+    text = result.get("text")
+    language = result.get("language")
+    print('mic:', text, language)
+
+# マイク転写を開始（別スレッドで動く）
+model.startMicTranscript(on_mic_result)
+
+# 一度だけ翻訳を呼ぶ
+translation, success = model.getInputTranslate('Hello', source_language='English')
+print('translation:', translation, 'success:', success)
+
+# WebSocket 経由で外部クライアントへイベント送信
+model.websocketSendMessage({'type': 'INFO', 'message': 'VRCT ready'})
+```
