feat: Add unified agent integration with Prometheus, Every Code, and Dexto

This commit adds comprehensive integration of three major AI agent platforms:

## MCP Servers (3)
- Prometheus MCP: Knowledge graph code reasoning with AST analysis
- Every Code MCP: Fast terminal-based coding agent with Auto Drive
- Dexto MCP: Agent harness with orchestration and session management

## Claude Code Skills (6)
- /agent-plan: Generate implementation plans
- /agent-fix-bug: Fix bugs end-to-end
- /agent-solve: Solve complex problems
- /agent-review: Review code quality
- /agent-context: Get code context
- /agent-orchestrate: Orchestrate workflows

## Ralph Auto-Integration
- Pattern-based auto-trigger for all three platforms
- Intelligent backend selection
- Multi-platform coordination
- Configuration in ralph/ralph.yml

## Documentation
- Complete integration guides
- Ralph auto-integration documentation
- Setup scripts
- Usage examples

+# Prometheus MCP Server
+
+MCP (Model Context Protocol) server for the Prometheus AI code reasoning platform.
+
+## Features
+
+- Knowledge graph queries via Neo4j
+- AST-based code search using Tree-sitter
+- File operations (read, create, edit)
+- Issue classification (bug/feature/question/doc)
+- Codebase Q&A with context retrieval
+
+## Installation
+
+```bash
+pip install prometheus-mcp
+```
+
+## Usage
+
+### As a standalone server
+
+```bash
+prometheus-mcp --repo /path/to/codebase
+```
+
+### With Claude Code
+
+Add to your `~/.config/claude-code/config.json`:
+
+```json
+{
+  "mcpServers": {
+    "prometheus": {
+      "command": "prometheus-mcp",
+      "args": ["--repo", "/path/to/your/repo"]
+    }
+  }
+}
+```
+
+## Available Tools
+
+### Knowledge Graph Tools
+
+- `prometheus_find_file` - Find files by basename
+- `prometheus_search_code` - Search code by text
+- `prometheus_search_docs` - Search documentation
+
+### File Operations
+
+- `prometheus_read_file` - Read file with line numbers
+- `prometheus_create_file` - Create new file
+- `prometheus_edit_file` - Edit file (exact string replacement)
+
+### Agent Tools
+
+- `prometheus_classify_issue` - Classify GitHub issues
+- `prometheus_answer_question` - Answer codebase questions
+
+## Development
+
+```bash
+# Install development dependencies
+pip install -e ".[dev]"
+
+# Run tests
+pytest
+
+# Format code
+black prometheus_mcp/
+
+# Type check
+mypy prometheus_mcp/
+```
