让 VNote 具备接入 AI 的能力

VNote stores notes as local Markdown files, making it an excellent candidate for AI-assisted knowledge management. However, unlike Obsidian, VNote currently has no way for AI programming agents (such as opencode, Claude Code, Cursor, etc.) to read, write, search, or manage notes programmatically. Users who want to use VNote as an AI agent knowledge base are forced to rely on file system-level hacks.
