* Add napkin plugin: visual whiteboard collaboration for Copilot CLI
Napkin opens an interactive HTML whiteboard in the user's browser where
they can draw, sketch, and add sticky notes. When ready, they click
'Share with Copilot' which exports a PNG snapshot. The Copilot CLI agent
reads the PNG via the view tool, and the multimodal AI model interprets
the drawings, spatial layout, and text content — responding
conversationally as a collaborator.
Built for non-technical users: lawyers, PMs, business stakeholders,
designers, and anyone who thinks better visually.
Includes:
- Self-contained HTML whiteboard (zero external dependencies)
- Shape recognition (wobbly shapes snap to clean versions)
- Freehand drawing, sticky notes, arrows, text labels
- Auto-save to localStorage
- SKILL.md with agent instructions
- SVG visual guides for step-by-step README documentation
- Plugin manifest for Copilot CLI installation

* Add missing Line (L) and Eraser (E) keyboard shortcuts to README
The in-app shortcuts panel and keyMap handler both support L for Line
and E for Eraser, but the README keyboard shortcuts table was missing
both entries. Adds them to match the actual implementation.
