Refactor and add disclaimer to README

Changes:
- Clean up code comments and improve readability
- Use datetime.timezone instead of zoneinfo for JST handling
- Add disclaimer section warning about AISEG2 device load
- Emphasize self-responsibility and appropriate interval settings
- Note unofficial status of the tool

 AISEG2 → MQTT Discovery (per-circuit daily kWh)
-- ブログ記載コードと等価のスクレイピング手順

-  * 総量: /page/graph/52111, 53111, 54111, 51111 の <span id="val_kwh"> 先頭
-  * 回路一覧: /page/setting/installation/734 の window.onload JSON(arrayCircuitNameList, strBtnType=="1")

 - MQTT:
-  * Discovery/config は retain=True
-  * state も retain=True（初回/再起動時に確実に値付与）
-  * 送信は publish → wait_for_publish() でACK待ち（sleep不要）
-- エンティティID: object_id で回路番号固定（sensor.c{ID}）
-- 単発実行想定（定期実行は HA Automation / cron 推奨）
+  * Discovery/config: retain=True
+  * state: retain=True（HA再起動後も直ちに当日値を復元）
+  * publishはACK待ち（wait_for_publish）、sleep不使用
+- エンティティID: object_id を "aiseg2mqtt_..." として固定（例: sensor.aiseg2mqtt_c12）
