docs: Add Phase 2 core package documentation (Execution, Config, Runtime, Security)

Comprehensive documentation for 7 critical packages covering execution engine, configuration management, runtime infrastructure, and security layers. Package Documentation Added: - pkg/execution - Complete task execution engine API (Docker sandboxing, image selection) - pkg/config - Configuration management (80+ env vars, dynamic assignments, SIGHUP reload) - internal/runtime - Shared P2P runtime (initialization, lifecycle, agent mode) - pkg/dht - Distributed hash table (LibP2P DHT, encrypted storage, bootstrap) - pkg/crypto - Cryptography (age encryption, key derivation, secure random) - pkg/ucxl - UCXL validation (decision publishing, content addressing, immutable audit) - pkg/shhh - Secrets management (sentinel, pattern matching, redaction, audit logging) Documentation Statistics (Phase 2): - 7 package files created (~12,000 lines total) - Complete API reference for all exported symbols - Line-by-line source code analysis - 30+ usage examples across packages - Implementation status tracking (Production/Beta/Alpha/TODO) - Cross-references to 20+ related documents Key Features Documented: - Docker Exec API usage (not SSH) for sandboxed execution - 4-tier language detection priority system - RuntimeConfig vs static Config with merge semantics - SIGHUP signal handling for dynamic reconfiguration - Graceful shutdown with dependency ordering - Age encryption integration (filippo.io/age) - DHT cache management and cleanup - UCXL address format (ucxl://) and decision schema - SHHH pattern matching and severity levels - Bootstrap peer priority (assignment > config > env) - Join stagger for thundering herd prevention Progress Tracking: - PROGRESS.md added with detailed completion status - Phase 1: 5 files complete (Foundation) - Phase 2: 7 files complete (Core Packages) - Total: 12 files, ~16,000 lines documented - Overall: 15% complete (12/62 planned files) Next Phase: Coordination & AI packages (pkg/slurp, pkg/election, pkg/ai, pkg/providers) 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com>

+
+## Documentation Standards
+
+### Format Consistency
+
+All package docs follow standard structure:
+1. Header (package, files, status, purpose)
+2. Overview
+3. Package Interface (exports)
+4. Core Types (detailed)
+5. Implementation Details
+6. Configuration
+7. Usage Examples (3+)
+8. Implementation Status
+9. Error Handling
+10. Related Documentation
+
+### Markdown Features Used
+
+- ✅ Tables for structured data
+- ✅ Code blocks with syntax highlighting
+- ✅ ASCII diagrams for flows
+- ✅ Emoji for status indicators
+- ✅ Internal links (relative paths)
+- ✅ External links (full URLs)
+- ✅ Collapsible sections (where supported)
+- ✅ Status badges
+
+### Status Indicators
+
+- ✅ **Production** - Fully implemented, tested
+- 🔶 **Beta** - Functional, testing in progress
+- 🔷 **Alpha** - Basic implementation, experimental
+- ⏳ **Stubbed** - Interface defined, placeholder
+- ❌ **TODO** - Planned but not implemented
+- ⚠️ **Deprecated** - Scheduled for removal
+
+---
+
+## Notes for Continuation
+
+### Context Management
+
+Due to token limits, documentation is being created in phases:
+- Use `TodoWrite` to track progress
+- Commit frequently (every 3-5 files)
+- Reference completed docs for consistency
+- Use agents for parallel documentation
+
+### Quality Checks
+
+Before marking complete:
+- [ ] All exported symbols documented
+- [ ] Line numbers referenced for code
+- [ ] Minimum 3 usage examples
+- [ ] Implementation status marked
+- [ ] Cross-references bidirectional
+- [ ] No broken links
+- [ ] Consistent formatting
+
+### Conversion to HTML
+
+When complete, use pandoc:
+```bash
+cd docs/comprehensive
+pandoc -s README.md -o index.html --toc --css=style.css
+# Repeat for all .md files
+```
