feat(merge): 以官方 main 为基底融合 PR#530 多维表格与本地定制

- 多维表格（canvas-batch-table-node/use-canvas-batch-table/canvas-batch-table 等）以 PR#530 实现为主
- 保留官方 main 全部新功能：banner/画布版本历史/提示词编辑/方舟 Agent Plan/支付导出
- 移植本地定制：ddcat 多参考图校验、万有引力 lxmone 连接错误提示、Description v20(v24)、自建插件(a6api/metaso-h3/antigravity-proxy/lxmone)、seccomp、Windows 脚本
- 迁移版本升至 v24（官方 v20-23 banner/版本历史 + 我们的 Description 列）
- 修复官方缺失的 markdownPlainText import
