feat: Add installation tool, Claude.ai export, and skill standardization (#1)

## Summary

- Add portable installation tool (`install.sh`) for cross-machine setup
- Add Claude.ai export files with proper YAML frontmatter
- Add multi-agent-guide v2.0 with consolidated framework template
- Rename `00-claude-code-setting` → `00-our-settings-audit` (avoid reserved word)
- Add YAML frontmatter to 25+ SKILL.md files for Claude Desktop compatibility

+# Claude Code Settings Optimizer
+
+Self-audit and optimize Claude Code configuration for maximum token efficiency and performance.
+
+## Core Focus
+
+1. **Token Budget Management** - Keep baseline under 30% of 200K context
+2. **MCP Tool Loading Strategy** - Essential tools always, others lazy-loaded
+3. **CLAUDE.md Optimization** - Concise, structured, under 200 lines
+4. **Context Preservation** - Maintain original prompt context throughout session
+
+## Quick Commands
+
+```bash
+# Run full audit
+python3 scripts/run_audit.py
+
+# Check token usage only
+python3 scripts/analyze_tokens.py
+
+# Auto-fix with preview
+python3 scripts/auto_fix.py
+
+# Apply fixes
+python3 scripts/auto_fix.py --apply
+```
+
+## Audit Scope
+
+### 1. Token Usage Analysis
+
+| Component | Target | Max | Action if Exceeded |
+|-----------|--------|-----|-------------------|
+| CLAUDE.md | 2,000 | 3,000 | Compress/split |
+| MCP Servers | 5,000 | 10,000 | Enable Tool Search, add serverInstructions |
+| Skills metadata | 500 | 1,000 | Reduce descriptions |
+| **Working space** | **>140,000** | — | Goal: 70%+ available |
+
+### 2. MCP Server Strategy
+
+**Load Strategy Classification:**
+
+| Strategy | Criteria | Action |
+|----------|----------|--------|
+| `always` | Essential for daily work (Playwright, Notion) | Keep loaded |
+| `lazy` | Occasionally needed (GitHub, Slack) | Load on demand |
+| `disable` | Rarely used or token-heavy (Zapier 50+ tools) | Turn off |
+
+**Critical Check:** Every MCP server MUST have `serverInstructions` for Tool Search to work efficiently.
+
+### 3. CLAUDE.md Health
+
+Check for:
+- Line count (warn >200)
+- Token estimate (warn >3,000)
+- Structure quality (headers, lists vs wall of text)
+- Redundant information
+- Information Claude already knows (don't repeat)
+
+### 4. Extension Efficiency
+
+- Commands: Has frontmatter? Under 100 lines?
+- Skills: SKILL.md present? Under 500 lines?
+- Agents: Tools restricted appropriately?
+
+## Output Report
+
+```markdown
+# Claude Code Settings Audit
+
+## Token Budget
+- Baseline usage: X / 200,000 (Y%)
+- Available for work: Z tokens
+
+## Health Status
+- Overall: [Good/Needs Attention/Critical]
+- MCP Servers: X configured, Y missing instructions
+- CLAUDE.md: X lines, ~Y tokens
+
+## Findings
+### Critical (must fix)
+### Warnings (should fix)
+### Passing (good)
+
+## Recommendations
+[Prioritized action items]
+```
+
+## Auto-Fix Capabilities
+
+Safe fixes applied automatically (with backup):
+- Add `serverInstructions` to MCP servers
+- Add frontmatter to commands missing it
+- Suggest CLAUDE.md compression
+
+Manual review required:
+- Disabling MCP servers
+- Restructuring CLAUDE.md content
+- Removing unused extensions
+
+## Best Practices
+
+### Token Optimization Principles
+
+1. **CLAUDE.md**: Only include what Claude doesn't already know
+2. **MCP Servers**: Use `serverInstructions` for Tool Search discovery
+3. **Skills**: Keep SKILL.md brief, details in `references/`
+4. **Context**: Run `/compact` at 70% usage, `/clear` between unrelated tasks
+
+### Ideal Configuration
+
+```
+Context Budget: 200,000 tokens
+├── System prompt: ~5,000 (fixed)
+├── CLAUDE.md: ~2,000 (your control)
+├── MCP tools: ~5,000 (with Tool Search)
+├── Skills: ~500 (metadata only)
+└── Available: ~187,500 (93.75%)
