feat: add ExternalScout and optimize ContextScout with research-backed patterns (#128)
* feat: add ExternalScout and optimize ContextScout with research-backed patterns

## New Features

### ExternalScout Subagent (v2.0.0)
- Fetches live, version-specific documentation for external libraries via Context7 API
- Supports 18+ libraries: Drizzle, Better Auth, Next.js, TanStack, Cloudflare Workers, AWS Lambda, Vercel, Shadcn/ui, Radix UI, Tailwind CSS, Zustand, Jotai, Zod, React Hook Form, Vitest, Playwright
- Lazy-loads query patterns for specific libraries only
- Filters and formats results by relevance (Critical → High → Medium)
- Fallback to official docs via webfetch
- 42% token reduction via research-backed optimization
- Added to registry with skill:context7 dependency

### Context7 Skill
- Registered in system for external documentation fetching
- Library registry with 18+ supported libraries
- Query optimization patterns per library
- Navigation guide and README

## Optimizations

### ContextScout v5.1.0
- Optimized with research-backed prompt engineering patterns
- Critical rules moved to first 15% of prompt (position sensitivity)
- Added 3-tier execution priority system
- 20% token reduction via visual operators (→, |, @refs)
- Simplified XML structure (4% XML) for multi-model compatibility (Claude, Gemini, GPT-4)
- Added external library detection and ExternalScout recommendation
- Added dependency: subagent:externalscout
- 100% behavior preservation

### ExternalScout v2.0.0 Optimizations
- 42% token reduction via visual operators and inline mappings
- Critical rules moved to first 15% of prompt
- Added 3-tier execution priority system
- Added references to prompt engineering docs and context system
- Enhanced workflow structure with checkpoints
- Added dependencies: context:prompt-engineering, context:context-system

## Registry Updates
- Added ExternalScout subagent entry
- Added Context7 skill entry
- Updated ContextScout dependencies to include ExternalScout

# External Library Registry
## Purpose
This file lists external libraries/frameworks that should use **ExternalScout** (via Context7) for live documentation instead of relying on potentially outdated training data.
## When to Use This
**ContextScout** checks this list when:
1. User asks about a library/framework
2. No internal context exists in `.opencode/context/development/frameworks/`
3. Query matches a library name below
**Action**: Recommend **ExternalScout** subagent

## Detection Patterns
ContextScout and ExternalScout should match queries containing:
- Library name (case-insensitive)
- Common variations (e.g., "next.js" vs "nextjs")
- Package names (e.g., "@tanstack/react-query")
**Examples**:
- "How do I use **Drizzle** with PostgreSQL?" → Match: Drizzle ORM
- "Show me **Next.js** App Router setup" → Match: Next.js
- "**TanStack Query** with Server Components" → Match: TanStack Query
- "**Better Auth** integration" → Match: Better Auth

## Adding New Libraries
To add a new library:
1. Add entry under appropriate category
2. Include: Name, aliases, docs link, Context7 command, common topics
3. (Optional) Add query optimization patterns
4. Update ExternalScout if needed (usually automatic)
**Template**:
```markdown
#### Library Name
- **Aliases**: `alias1`, `alias2`, `package-name`
- **Docs**: https://example.com/docs
- **Context7**: `use context7 for library-name`
- **Common topics**: topic1, topic2, topic3
```
---
## Usage by ExternalScout
ExternalScout uses this file to:
1. **Detect** which library the user is asking about
2. **Load** query optimization patterns for that library
3. **Build** optimized Context7 queries
4. **Fetch** live documentation
5. **Return** filtered, relevant results
