Keep image payloads out of persistent agent history by storing vision and
computer-use captures as file path references instead of inline base64 data.
- update vision_load to attach image paths without compression or JPEG conversion
- update computer_use_remote to attach shared capture artifact paths directly
- serialize local image refs into provider-valid data URLs only at request prep
- reject base64/data URL attachments on the connector WebSocket path
- advertise path_or_url as the connector attachment mode
- Move load_classes_from_file and load_classes_from_folder from extract_tools to new modules helper
- Update all imports across api, extension, files, and plugins to use helpers.modules
- Add namespace purging to refresh_plugin_modules for selective plugin reload on Python changes
- Implement embed trimming in history based on model config max_embeds and vision support
- Add pre_update hook documentation to plugin
- Reset retry counter to 0 when exception is None or already handled (HandledException, RepairableException)
- Add text message to vision_load tool results to prevent model provider errors with image-only messages
