HistoPilot updates: domain approval, uploads, and slide conversion

I have been continuing work on HistoPilot. Here are a few recent updates.

The ICP filing for histopilot.cn has been approved. HistoPilot will use this domain to provide services in the future. The domain switch and deployment are next.

The main COS direct-upload implementation and its code tests are complete, and deployment is being prepared. The browser sends large files to object storage, then the platform handles validation, processing, and import. Before opening it up, I will continue testing real uploads, capacity settings, and failure recovery with more sample files.

I have also added a frontend slide conversion module for converting file formats in the browser, starting with KFB/KFBF. The workflow lets users save the converted file locally or upload it to the workspace. The conversion core and browser runner have been through an initial round of validation; the interface and compatibility are still being adjusted. Most of this implementation was built with help from Opus 5.5. More browser and real-device testing will follow.

Other work now includes AIVC training and research in directions similar to Anthropic's Model Hardware Standard (MHS). I may post further updates on these projects here.
