[WIP] Add simple default README for Note Board tool

[Copilot]

• Inspect repository structure and existing docs/build-test commands
• Summarize understanding of the requested default README
• Update the README and any directly related docs with a minimal, focused change
• Add or adjust tests only if existing documentation/test infrastructure applies
• Run targeted validation and manually verify the updated documentation
• Run final review/security validation and report results

Original prompt

create simple default readme ---> we want to emulate the popular 'note board' tool that theo from t3.gg is always showing in his videos ---> but its a barebones one page with a backend mcp server implementation that supports agentic use, and includes base skill.md ----> websites designed primarily for humans to easily architect up cleanly a clear architecture diagram with drag and drop objects that are readable by agent (as svg schema) and included with relevant instruction text from human user (or agent user whatever) ---> first provide me summary of your understanding and clean action plan please.
