Conversation
Add the ability to set and edit alt text on images via the editor's image bubble menu. This improves accessibility and enables better markdown export (e.g. for RAG systems). Changes: - Add an "Alt text" button to the image bubble menu toolbar - Show an inline text input for editing alt text on click - Fix image-view.tsx to use the `alt` attribute instead of `title` Closes docmost#1736 Co-Authored-By: Claude Opus 4.6 (1M context) <[email protected]>

Summary
Adds image caption support to the editor, as requested in #1736. Following @Philipinho's suggestion, this uses a visible caption below the image instead of a hidden alt text field. The caption text is also used as the
