Reorganize: Move all skills to skills/ folder

- Created skills/ directory
- Moved 272 skills to skills/ subfolder
- Kept agents/ at root level
- Kept installation scripts and docs at root level

Repository structure:
- skills/           - All 272 skills from skills.sh
- agents/           - Agent definitions
- *.sh, *.ps1       - Installation scripts
- README.md, etc.   - Documentation

+# Design and Refine
+
+Generate UI design variations, collect feedback, synthesize the best elements, and iterate to confident design decisions.
+
+## Installation
+
+### Local Testing
+
+```bash
+claude --plugin-dir /path/to/design-variations-plugin
+```
+
+### From Marketplace
+
+```bash
+/plugin marketplace add 0xdesigner/design-plugin
+/plugin install design-and-refine@design-plugins
+```
+
+## Commands
+
+### `/design-and-refine:start [target]`
+
+Start a design and refine session.
+
+**Arguments:**
+- `target` (optional): Component or page to design/redesign
+
+**Example:**
+```
+/design-and-refine:start CheckoutSummary
+/design-and-refine:start
+```
+
+### `/design-and-refine:cleanup`
+
+Remove all temporary design lab files.
+
+## How It Works
+
+1. **Preflight**: Detects framework, package manager, styling system
+2. **Style Inference**: Reads your existing design tokens and patterns
+3. **Interview**: Asks about requirements, pain points, and direction
+4. **Generate**: Creates 5 distinct variations using your project's visual language
+5. **Review**: Preview variants side-by-side at `/__design_lab`
+6. **Feedback**: Tell me what you like about each variant
+7. **Synthesize**: Creates a refined version combining the best elements
+8. **Iterate**: Repeat until you're confident
+9. **Finalize**: Cleans up temp files, produces `DESIGN_PLAN.md`
+
