Feature Request: Optional Native Markdown Source Mode

I'd love to see an optional native Markdown editing mode in Capacities, similar to the source editing experience in Obsidian.

As a software developer, I frequently write technical documentation involving code snippets, headings, lists, tables, and links. Writing directly in Markdown is often significantly faster and more predictable than working exclusively with a block-based rich-text editor. Ideally, users could toggle between the existing visual editor and a raw Markdown source view without losing content, formatting, or Capacities-specific features. I particularly value Capacities for its browser accessibility, object-based knowledge management, and integrated task management. I'm not looking to replace these features, but to complement them with a more developer-friendly editing experience.

An optional Markdown source mode would make Capacities even more attractive for software engineers and technically oriented users.
