Add mengram-setup skill

[Zenlyte]

Description

A self-hosted Mengram memory system skill for AI agents on Zo Computer. Mengram provides human-like memory with semantic (facts), episodic (events), and procedural (workflows) memory types, combining knowledge graph storage with hybrid retrieval.

Features

• 🧠 Three Memory Types: Semantic facts, episodic events, and procedural workflows
• 🔍 Hybrid Search: Vector similarity + knowledge graph traversal
• 📈 Procedure Evolution: Workflows automatically improve from failures
• 🔐 Security: API key authentication for all endpoints
• 🏠 Fully Local: Ollama for LLM, local embeddings, SQLite storage
• 🤖 Zo Integration: Includes CLI tools, REST API, and automation setup guide

Use Cases

• Conversational agent memory that learns from natural language
• Personal knowledge bases built from notes and conversations
• User preference tracking extracted from chat interactions
• Procedural memory that evolves based on experience

Testing

• Validated skill structure with `bun validate` (no errors)
• Verified all PII is sanitized (author field, API keys are placeholders)
• Tested setup.py installation script and REST API endpoints
• Confirmed CLI tools work correctly (mengram.py, mengram_memory.py)

Checklist

• SKILL.md has required frontmatter (name, description, metadata.author)
• Skill directory name matches `name` in frontmatter
• Description clearly explains when to use the skill
• No sensitive data (API keys, tokens) included
• `bun validate` passes
• Includes Zo automation setup guide (rules, personas, agents)
