feat: implement swarm agents with hierarchical collaboration and vector memory

This commit introduces a multi-agent Swarm Engine to PicoClaw,
enabling complex task orchestration through autonomous collaboration and long-term
semantic memory.

Key Features:
- Actor Model Architecture: Every agent (node) runs in an isolated goroutine,
  communicating via a lightweight internal Event Bus.
- Hierarchical Delegation: Manager nodes can dynamically spawn specialized
  worker nodes (Researchers, Analysts, etc.) to perform sub-tasks in parallel.
- Hybrid Memory System: Combined SQLite for state persistence and Chromem-go
  for a persistent, cross-swarm Vector Knowledge Base.
- Progressive Summarization: Implemented an intelligent memory pruning mechanism
  that summarizes older context before truncation to preserve findings without
  exceeding token limits.
- Role-Based Access Control (RBAC): Configurable tool policies per role
  (e.g., Researchers can browse but not execute shell commands).

Performance & Scaling:
- Low Footprint: Idle memory usage is ~7-8 MB RSS.
- Efficient Scaling: During a stress test with 10 concurrent agents performing
  intensive research, memory usage peaked at only 27 MB.
- Per-Node Cost: Each active agent consumes approximately 0.6 MB to 2 MB of
  physical RAM depending on conversation length and summarization state.
- Stability: Successfully handled 10 parallel LLM requests with zero race
  conditions, showcasing the robustness of the Go-based Actor model.

Integration:
- Native CLI Support: Added /swarm spawn, /swarm list, and /swarm status commands.
- Mermaid Visualization: Support for /swarm viz <id> to generate organizational
  charts of active agent hierarchies.
- Configurable: Roles, models, and security policies are fully customizable
  via config.json.

+# PicoClaw Swarm Engine
+
+This package implements the **Swarm Agents** architecture: a lightweight, hierarchical, multi-agent system designed for the edge.
+
+For a detailed deep-dive into the architecture, workflow, and components, please read [SWARM_ARCHITECTURE.md](../../SWARM_ARCHITECTURE.md).
+
+## Features
+
+*   **Hierarchical Swarms:** Manager nodes can delegate tasks to specialized workers (Researchers, Writers, etc.).
+*   **Vector Memory:** Integrated `Chromem-go` vector database for long-term semantic memory.
+*   **Resilient:** Built-in retry mechanisms, context pruning, and crash recovery via SQLite checkpoints.
+*   **Secure:** Configurable Role-Based Access Control (RBAC) for tools.
+*   **Lightweight:** Built on Go Goroutines (Actor Model) and Channels, efficient enough for small VPS or local devices.
+
+## Usage
+
+The Swarm Engine is integrated into the PicoClaw CLI.
+
+### Basic Commands
+
+```bash
+# Spawn a new swarm to perform a task
+/swarm spawn "Analyze the latest trends in Rust vs Go performance"
+
+# List active swarms
+/swarm list
+
+# Check detailed status of a specific swarm (including node progress)
+/swarm status <swarm_id>
+
+# Visualize the swarm topology (Mermaid diagram)
+/swarm viz <swarm_id>
+
+# Stop a running swarm
+/swarm stop <swarm_id>
+```
+
+### Configuration
+
+You can configure the Swarm behavior, Roles, and Policies in your `config.json`.
+
+```json
+{
+  "swarm": {
+    "limits": {
+      "max_nodes": 10,
+      "global_timeout": 600000000000, 
+      "max_iterations": 15
+    },
+    "roles": {
+      "Manager": {
+        "description": "Orchestrates tasks",
+        "system_prompt": "You are a Manager...",
+        "tools": ["delegate_task", "save_memory", "search_memory"]
+      }
+    },
+    "policies": [
+      {
+        "role": "Manager",
+        "allowed": ["*"]
+      }
+    ]
+  }
+}
+```
+
+## Architecture Overview
+
+```mermaid
+graph TD
+    Service --> Orchestrator
+    Orchestrator --> Manager[Manager Node]
+    Manager -->|Delegates| Worker[Worker Node]
+    Manager <-->|Memory| VectorDB[(Vector DB)]
