feat: RoutingWorkflow + LLM Router + Memory Activity

- Add RoutingWorkflow: generic state machine executor for WorkflowSpec
- Add LLM Router: natural language → WorkflowSpec generation
- Add RetrieveMemoryActivity: query poimen-memory for context
- Add activities: AnalyzeCode, SecurityScan, GenerateReport, Notify, etc.
- Add agent-prompts/router: LLM prompt documentation
- Extend starter with --route flag for routing workflows
- Remove orchestrator job (trigger via API/message instead)
- Clean up: move docs to Desktop, add .gitignore for *.md

+
+## Memory Integration
+
+Router receives context from `RetrieveMemoryActivity`:
+
+```
+1. User: "scan repo for security"
+2. RetrieveMemoryActivity queries poimen-memory
+3. Returns: skills, lessons, references
+4. Injected into Router prompt
+5. Router generates smarter WorkflowSpec
+```
