feat: Implement council brief processing loop for task execution

Add processBriefs() polling loop that checks for assigned council briefs
and executes them using the ExecutionEngine infrastructure.

Changes:
- Add GetCurrentAssignment() public method to council.Manager
- Make HTTPServer.CouncilManager public for brief access
- Add processBriefs() 15-second polling loop in agent_support.go
- Add executeBrief() to initialize and run ExecutionEngine
- Add buildExecutionRequest() to convert briefs to execution requests
- Add uploadResults() to send completed work to WHOOSH
- Wire processBriefs() into StartAgentMode() as background goroutine

This addresses the root cause of task execution not happening: briefs
were being stored but never polled or executed. The execution
infrastructure (ExecutionEngine, AI providers, prompt system) was
complete but not connected to the council workflow.

+# LightRAG MCP Integration
+
+**Status:** ✅ Production Ready
+**Version:** 1.0.0
+**Date:** 2025-09-30
+
+## Overview
+
+CHORUS now includes optional LightRAG integration for Retrieval-Augmented Generation (RAG) capabilities. LightRAG provides graph-based knowledge retrieval to enrich AI reasoning and context resolution.
+
+## Architecture
+
+### Components
+
+1. **LightRAG Client** (`pkg/mcp/lightrag_client.go`)
+   - HTTP client for LightRAG MCP server
+   - Supports 4 query modes: naive, local, global, hybrid
+   - Health checking and document insertion
+   - Configurable timeouts and API authentication
+
+2. **Reasoning Engine Integration** (`reasoning/reasoning.go`)
+   - `GenerateResponseWithRAG()` - RAG-enriched response generation
+   - `GenerateResponseSmartWithRAG()` - Combines model selection + RAG
+   - `SetLightRAGClient()` - Configure RAG client
+   - Non-fatal error handling (degrades gracefully)
+
+3. **SLURP Context Enrichment** (`pkg/slurp/context/lightrag.go`)
+   - `LightRAGEnricher` - Enriches context nodes with RAG data
+   - `EnrichContextNode()` - Add insights to individual nodes
+   - `EnrichResolvedContext()` - Enrich resolved context chains
+   - `InsertContextNode()` - Build knowledge base over time
+
+4. **Configuration** (`pkg/config/config.go`)
+   - `LightRAGConfig` struct with 5 configuration options
+   - Environment variable support
+   - Automatic initialization in runtime
+
+## Configuration
+
+### Environment Variables
+
+```bash
+# Enable LightRAG integration

+
+## Query Modes
+
+LightRAG supports 4 query modes with different retrieval strategies:
+
+1. **Naive Mode** (`QueryModeNaive`)
+   - Simple semantic search
+   - Fastest, least context
+   - Use for: Quick lookups
+
+2. **Local Mode** (`QueryModeLocal`)
+   - Local graph traversal
+   - Context from immediate neighbors
+   - Use for: Related information
+
+3. **Global Mode** (`QueryModeGlobal`)
+   - Global graph analysis
+   - Broad context from entire knowledge base
+   - Use for: High-level questions
+
+4. **Hybrid Mode** (`QueryModeHybrid`) ⭐ **Recommended**
+   - Combined approach
+   - Balances breadth and depth
+   - Use for: General purpose RAG
+
+## Usage Examples
+
+### Reasoning Engine with RAG
+
+```go
+import (
+    "context"
+    "chorus/reasoning"
+    "chorus/pkg/mcp"
+)
+
+// Initialize LightRAG client
+config := mcp.LightRAGConfig{
+    BaseURL: "http://127.0.0.1:9621",
+    Timeout: 30 * time.Second,
+}
+client := mcp.NewLightRAGClient(config)
+
+// Configure reasoning engine
+reasoning.SetLightRAGClient(client)
+
+// Generate RAG-enriched response
+ctx := context.Background()
+response, err := reasoning.GenerateResponseWithRAG(
+    ctx,
+    "meta/llama-3.1-8b-instruct",
+    "How does CHORUS handle P2P networking?",
+    mcp.QueryModeHybrid,
+)
+```
+
+### SLURP Context Enrichment
+
+```go
+import (
+    "context"
+    "chorus/pkg/slurp/context"
+    "chorus/pkg/mcp"
+)
+
+// Create enricher
+enricher := context.NewLightRAGEnricher(client, "hybrid")
+
+// Enrich a context node
+node := &context.ContextNode{
+    Path:    "/pkg/p2p",
+    Summary: "P2P networking implementation",
+    Purpose: "Provides libp2p networking layer",
+}
+
+err := enricher.EnrichContextNode(ctx, node)
+// node.Insights now contains RAG-retrieved information
+
+// Insert for future retrieval
+err = enricher.InsertContextNode(ctx, node)
+```
+
+### Direct LightRAG Client
+
+```go
+import (
+    "context"
+    "chorus/pkg/mcp"
+)
+
+client := mcp.NewLightRAGClient(config)
+
+// Health check
+healthy := client.IsHealthy(ctx)
+
+// Query with response
+response, err := client.Query(ctx, "query", mcp.QueryModeHybrid)
+
+// Get context only
+context, err := client.GetContext(ctx, "query", mcp.QueryModeHybrid)
+
+// Insert document
+err := client.Insert(ctx, "text content", "description")
+```
+
+## Integration Points
+
+### Runtime Initialization
+
+LightRAG is initialized automatically in `internal/runtime/shared.go`:
+
+```go
+// Line 685-704
+if cfg.LightRAG.Enabled {
+    lightragConfig := mcp.LightRAGConfig{
+        BaseURL: cfg.LightRAG.BaseURL,
+        Timeout: cfg.LightRAG.Timeout,
+        APIKey:  cfg.LightRAG.APIKey,
+    }
+    lightragClient := mcp.NewLightRAGClient(lightragConfig)
+
+    if lightragClient.IsHealthy(ctx) {
+        reasoning.SetLightRAGClient(lightragClient)
+        logger.Info("📚 LightRAG RAG system enabled")
+    }
+}
+```
+
+### Graceful Degradation
+
+LightRAG integration is **completely optional** and **non-blocking**:
+
+- If `CHORUS_LIGHTRAG_ENABLED=false`, no LightRAG calls are made
+- If LightRAG server is unavailable, health check fails gracefully
+- If RAG queries fail, reasoning engine falls back to non-RAG generation
+- SLURP enrichment failures are logged but don't block context resolution
+
+## Testing
+
+### Unit Tests
+
+```bash
+# Run all LightRAG tests (requires running server)
+go test -v ./pkg/mcp/
+
+# Run only unit tests (no server required)
+go test -v -short ./pkg/mcp/
+```
+
+### Integration Tests
+
+```bash
+# Start LightRAG server
+cd ~/chorus/mcp-include/LightRAG
+python main.py
+
+# Run integration tests
+cd ~/chorus/project-queues/active/CHORUS
+go test -v ./pkg/mcp/ -run TestLightRAGClient
+```
+
+## Performance Considerations
+
+### Query Timeouts
+
+- Default: 30 seconds
+- Hybrid mode is slowest (analyzes entire graph)
+- Naive mode is fastest (simple semantic search)
+
+### Caching
+
+LightRAG includes internal caching:
+- Repeated queries return cached results
+- Cache TTL managed by LightRAG server
+- No CHORUS-side caching required
+
+### Resource Usage
+
+- Memory: Proportional to knowledge base size
+- CPU: Query modes have different compute requirements
+- Network: HTTP requests to LightRAG server
+
+## Troubleshooting
+
+### Server Not Healthy
+
+**Symptom:** `LightRAG enabled but server not healthy`
+
+**Solutions:**
+1. Check if LightRAG server is running: `curl http://127.0.0.1:9621/health`
+2. Verify correct port in `CHORUS_LIGHTRAG_BASE_URL`
+3. Check LightRAG logs for errors
+4. Ensure network connectivity between CHORUS and LightRAG
+
+### Empty Responses
+
+**Symptom:** RAG queries return empty results
+
+**Solutions:**
+1. Knowledge base may be empty - insert documents first
+2. Query may not match indexed content
+3. Try different query mode (hybrid recommended)
+4. Check LightRAG indexing logs
+
+### Timeout Errors
+
+**Symptom:** `context deadline exceeded`
+
+**Solutions:**
+1. Increase `CHORUS_LIGHTRAG_TIMEOUT`
+2. Use faster query mode (naive or local)
+3. Optimize LightRAG server performance
+4. Check network latency
+
+## Security Considerations
+
+### API Authentication
+
+Optional API key support:
+```bash
+CHORUS_LIGHTRAG_API_KEY=your-secret-key
+```
+
+Keys are sent as Bearer tokens in Authorization header.
+
+### Network Security
+
+- Run LightRAG on internal network only
+- Use HTTPS for production deployments
+- Consider firewall rules to restrict access
+- LightRAG doesn't include built-in encryption
+
+### Data Privacy
+
+- All queries and documents are stored in LightRAG
+- Consider what data is being indexed
+- Implement data retention policies
+- Use access control on LightRAG server
+
+## Monitoring
+
+### Health Checks
+
+```go
+// Check LightRAG availability
+if client.IsHealthy(ctx) {
+    // Server is healthy
+}
+
+// Get detailed health info
+health, err := client.Health(ctx)
+// Returns: Status, CoreVersion, APIVersion, etc.
+```
+
+### Metrics
+
+Consider adding:
+- RAG query latency
+- Cache hit rates
+- Enrichment success/failure rates
+- Knowledge base size
+
+## Future Enhancements
+
+Potential improvements:
+
+1. **Batch Query Optimization**
+   - Batch multiple RAG queries together
+   - Reduce HTTP overhead
+
+2. **Adaptive Query Mode Selection**
+   - Automatically choose query mode based on question type
+   - Learn from past query performance
+
+3. **Knowledge Base Management**
+   - Automated document insertion from SLURP contexts
+   - Background indexing of code repositories
+   - Scheduled knowledge base updates
+
+4. **Advanced Caching**
+   - CHORUS-side caching with TTL
+   - Semantic cache (similar queries share cache)
+   - Persistent cache across restarts
+
+5. **Multi-tenant Support**
+   - Per-agent knowledge bases
+   - Role-based access to documents
+   - Encrypted knowledge storage
+
+## Files Changed
+
+1. `pkg/mcp/lightrag_client.go` - NEW (277 lines)
+2. `pkg/mcp/lightrag_client_test.go` - NEW (239 lines)
+3. `pkg/config/config.go` - Modified (added LightRAGConfig)

+5. `internal/runtime/shared.go` - Modified (added initialization)
+6. `pkg/slurp/context/lightrag.go` - NEW (203 lines)
+
+**Total:** 3 new files, 3 modified files, ~750 lines of code
