Ponderer - 思索者

新增功能 / New Features

• 结构列表、预览与子结构步骤：新增结构选择器与实时预览组件，show_structure / show_extra_structure 可直接浏览本地结构文件，并将额外结构作为子结构插入场景。 Added a structure picker with live previews, and expanded show_structure workflows with show_extra_structure so local structure files can be browsed and inserted as sub-structures in scenes.

• NBT 扩展编辑器：新增可展开的大型 NBT 文本编辑器，支持路径 / 坐标识别、多行输入增强，以及方块实体、实体、掉落物等步骤的 NBT 编辑与选取流程。 Added an expanded NBT editor with path/coordinate detection, improved multi-line editing, and better NBT edit/pick flows for block entities, entities, and item entities.

• 文本轨道与进度条：新增场景文本列表与文本标记指令，支持在 Ponder 播放过程中展示进度条、同步文本步骤，并改进共享文本的悬浮定位。 Added a scene text list and marker instructions for progress bars and synchronized text playback, while also improving floating shared-text positioning.

• 高级动画与界面回放：扩展 show_interface 的客户端截图 / 回放能力，并为区段、实体、掉落物等步骤补充外部动画与更细致的移动动画配置。 Expanded show_interface with client-side screen capture/replay, and added richer movement/external animation controls for sections, entities, and item entities.

改进 / Improvements

• 导出与脚本生成优化：重构 Java 导出模板与运行时支持代码，改进结构引用、导出结果反馈与清单生成，为复杂场景导出提供更稳定的产物。 Reworked Java export templates and runtime support generation, improving structure references, export feedback, and manifest output for more reliable complex-scene exports.

• 编辑器交互与缩放适配：新增 UI 缩放支持，优化长文本输入框、结构预览、旋转相机和多处步骤表单细节，提升大场景编辑体验。 Added dedicated UI scaling support and refined long text inputs, structure previews, rotate-camera controls, and multiple step forms for better large-scene editing.

修复 / Fixes

• 场景运行兼容性修复：修复合并区段后 hide_section 清理错误、Ponder 原生界面层级 / 文本索引问题，以及若干 NBT 选取与边界框相关回归。 Fixed merged-section hide_section cleanup, vanilla Ponder UI layering/text-index issues, and several regressions around NBT picking and scene bounds.
