feat: user-customizable event voice rules (gift/blind box/enter/follow/like/guard/super chat)

- New event_rules.py: load/save event_rules.json, robust template renderer
  (missing vars -> empty, empty template -> muted), guard level mapping
- danmaku_handler.py: custom SEND_GIFT callback to extract blind_gift_name;
  implements all event callbacks feeding the TTS queue per user rules
- server.py: GET/POST /api/rules, load rules at startup, pass to client
- Web UI: 'Event Voice Rules' panel (per-event toggle + template + save)
- main.py CLI loads rules; build.py bundles event_rules.json
- skip_free_gift option to mute silver free gifts
- Rebuild portable zip (83.8 MB)

+## 事件语音规则
+
+除弹幕外，礼物、盲盒、进房、上舰、醒目留言等事件也可以自定义语音。规则保存在 `event_rules.json`（首次运行自动生成），可在 Web UI 的 "Event Voice Rules" 面板编辑。
+
+模板为空字符串 = 该事件静音。`enabled` 控制整类事件开关，`skip_free_gift` 跳过银瓜子免费礼物。
