release: Ext.AiAssistant 1.0.0 重新打包（覆盖同名版本）

- 重新生成 Ext.AiAssistant-1.0.0.zip（Release 最新产物）
- index.json 同步 sha256/size；requiresHost 修正为 TeamPLT>=2.1.0（与 manifest 一致）
- 新增 regen-index.ps1：本仓库自带 index 重算（主仓库脚本路径写死，无法服务这里）

+# Regenerate index.json for THIS gallery repository (PLT\Gallery).
+#
+# 为什么自带一份：
+#   主仓库 build\regen-gallery-index.ps1 写死了 "<脚本父目录的父目录>\gallery"，
+#   只能服务 TeamAAS-2.1\gallery，无法指向这里。
+#
+# 格式：对齐远端 Gallery 仓库的 GalleryPackage schema（含多版本 versions[]），
+#   以保持内容为准：字段全部来自包内 manifest.json，不再手写，避免 index 与包不一致。
+#   版本历史会继承旧 index 中同 id 的其它版本条目（releasedAt / status / notes 不丢）。
+#
+# 用法（改了 packages\ 下任何 zip 之后执行）：
+#   powershell -NoProfile -ExecutionPolicy Bypass -File .\regen-index.ps1
+#
+# 布局约定：packages\<host>\<id>\<id>-<version>.zip（zip 根目录必须含 manifest.json）
