docs(mcp_client+ai_client): correct tool counts (15->18, 45->46)

- Total tool count: 45 -> 46 (per src/models.py:AGENT_TOOL_NAMES)
- Python AST tools: 15 -> 18 (3 structural mutators added:
  py_remove_def, py_add_def, py_move_def, py_region_wrap)
- py_get_symbol_info is fictional; replaced with the 4 actual
  structural mutator tools
- Cross-link from guide_ai_client.md updated

 ## Overview
 
-`src/mcp_client.py` (~81KB) is the **MCP (Model Context Protocol) tool implementation** for Manual Slop. It provides 45 tools that the AI can invoke to read/write files, analyze code structure, search symbols, and more.
+`src/mcp_client.py` (~81KB) is the **MCP (Model Context Protocol) tool implementation** for Manual Slop. It provides 46 tools that the AI can invoke to read/write files, analyze code structure, search symbols, and more. The canonical list lives in `models.AGENT_TOOL_NAMES` (`src/models.py:58`).
 
 The module implements the **client side** of MCP — it provides the tools that an AI model can call during a conversation. It also implements the project's strict filesystem security model.
